+ * <li>With a getter function, which can be used to manipulate stored values,

+ * <li>With a validator function, to validate values before they are stored.</li>

+ * The Date.Locale class is a container for all localised date strings
+ * used by Y.DataType.Date. It is used internally, but may be extended
+ * to provide new date localisations.
+ *
+ * To create your own Locale, follow these steps:
+ * <ol>
+ * <li>Find an existing locale that matches closely with your needs</li>
+ * <li>Use this as your base class. Use Y.DataType.Date.Locale["en"] if nothing
+ * matches.</li>
+ * <li>Create your own class as an extension of the base class using
+ * Y.merge, and add your own localisations where needed.</li>
+ * </ol>
+ * See the Y.DataType.Date.Locale["en-US"] and Y.DataType.Date.Locale["en-GB"]
+ * classes which extend Y.DataType.Date.Locale["en"].
+ *
+ * For example, to implement locales for French french and Canadian french,
+ * we would do the following:
+ * <ol>
+ * <li>For French french, we have no existing similar locale, so use
+ * Y.DataType.Date.Locale["en"] as the base, and extend it:
+ * <pre>
+ * Y.DataType.Date.Locale["fr"] = Y.merge(Y.DataType.Date.Locale, {
+ * a: ["dim", "lun", "mar", "mer", "jeu", "ven", "sam"],
+ * A: ["dimanche", "lundi", "mardi", "mercredi", "jeudi", "vendredi", "samedi"],
+ * b: ["jan", "fév", "mar", "avr", "mai", "jun", "jui", "aoû", "sep", "oct", "nov", "déc"],
+ * B: ["janvier", "février", "mars", "avril", "mai", "juin", "juillet", "août", "septembre", "octobre", "novembre", "décembre"],
+ * c: "%a %d %b %Y %T %Z",
+ * p: ["", ""],
+ * P: ["", ""],
+ * x: "%d.%m.%Y",
+ * X: "%T"
+ * });
+ * </pre>
+ * </li>
+ * <li>For Canadian french, we start with French french and change the meaning of \%x:
+ * <pre>
+ * Y.DataType.Date.Locale["fr-CA"] = Y.merge(Y.DataType.Date.Locale["fr"], {
+ * x: "%Y-%m-%d"
+ * });
+ * </pre>
+ * </li>
+ * </ol>
+ *
+ * With that, you can use your new locales:
+ * <pre>
+ * var d = new Date("2008/04/22");
+ * Y.DataType.Date.format(d, { format: "%A, %d %B == %x", locale: "fr" });
+ * </pre>
+ * will return:
+ * <pre>
+ * mardi, 22 avril == 22.04.2008
+ * </pre>

+ * To create your own Locale, follow these steps:
+ * <ol>
+ * <li>Find an existing locale that matches closely with your needs</li>
+ * <li>Use this as your base class. Use Y.DataType.Date.Locale["en"] if nothing
+ * matches.</li>
+ * <li>Create your own class as an extension of the base class using
+ * Y.merge, and add your own localisations where needed.</li>
+ * </ol>
+ * See the Y.DataType.Date.Locale["en-US"] and Y.DataType.Date.Locale["en-GB"]
+ * classes which extend Y.DataType.Date.Locale["en"].
+ *
+ * For example, to implement locales for French french and Canadian french,
+ * we would do the following:
+ * <ol>
+ * <li>For French french, we have no existing similar locale, so use
+ * Y.DataType.Date.Locale["en"] as the base, and extend it:
+ * <pre>
+ * Y.DataType.Date.Locale["fr"] = Y.merge(Y.DataType.Date.Locale, {
+ * a: ["dim", "lun", "mar", "mer", "jeu", "ven", "sam"],

+ * B: ["janvier", "février", "mars", "avril", "mai", "juin", "juillet", "août", "septembre", "octobre", "novembre", "décembre"],

+ * p: ["", ""],
+ * P: ["", ""],
+ * x: "%d.%m.%Y",
+ * X: "%T"
+ * });
+ * </pre>
+ * </li>
+ * <li>For Canadian french, we start with French french and change the meaning of \%x:
+ * <pre>
+ * Y.DataType.Date.Locale["fr-CA"] = Y.merge(Y.DataType.Date.Locale["fr"], {
+ * x: "%Y-%m-%d"
+ * });
+ * </pre>
+ * </li>
+ * </ol>
+ *
+ * With that, you can use your new locales:
+ * <pre>
+ * var d = new Date("2008/04/22");

+ * The Date.Locale class is a container for all localised date strings
+ * used by Y.DataType.Date. It is used internally, but may be extended
+ * to provide new date localisations.
+ *
+ * To create your own Locale, follow these steps:
+ * <ol>
+ * <li>Find an existing locale that matches closely with your needs</li>
+ * <li>Use this as your base class. Use Y.DataType.Date.Locale["en"] if nothing
+ * matches.</li>
+ * <li>Create your own class as an extension of the base class using
+ * Y.merge, and add your own localisations where needed.</li>
+ * </ol>
+ * See the Y.DataType.Date.Locale["en-US"] and Y.DataType.Date.Locale["en-GB"]
+ * classes which extend Y.DataType.Date.Locale["en"].
+ *
+ * For example, to implement locales for French french and Canadian french,
+ * we would do the following:
+ * <ol>
+ * <li>For French french, we have no existing similar locale, so use
+ * Y.DataType.Date.Locale["en"] as the base, and extend it:
+ * <pre>
+ * Y.DataType.Date.Locale["fr"] = Y.merge(Y.DataType.Date.Locale, {
+ * a: ["dim", "lun", "mar", "mer", "jeu", "ven", "sam"],
+ * A: ["dimanche", "lundi", "mardi", "mercredi", "jeudi", "vendredi", "samedi"],
+ * b: ["jan", "fév", "mar", "avr", "mai", "jun", "jui", "aoû", "sep", "oct", "nov", "déc"],
+ * B: ["janvier", "février", "mars", "avril", "mai", "juin", "juillet", "août", "septembre", "octobre", "novembre", "décembre"],
+ * c: "%a %d %b %Y %T %Z",
+ * p: ["", ""],
+ * P: ["", ""],
+ * x: "%d.%m.%Y",
+ * X: "%T"
+ * });
+ * </pre>
+ * </li>
+ * <li>For Canadian french, we start with French french and change the meaning of \%x:
+ * <pre>
+ * Y.DataType.Date.Locale["fr-CA"] = Y.merge(Y.DataType.Date.Locale["fr"], {
+ * x: "%Y-%m-%d"
+ * });
+ * </pre>
+ * </li>
+ * </ol>
+ *
+ * With that, you can use your new locales:
+ * <pre>
+ * var d = new Date("2008/04/22");
+ * Y.DataType.Date.format(d, { format: "%A, %d %B == %x", locale: "fr" });

+ * The Date.Locale class is a container for all localised date strings
+ * used by Y.DataType.Date. It is used internally, but may be extended
+ * to provide new date localisations.
+ *
+ * To create your own Locale, follow these steps:
+ * <ol>
+ * <li>Find an existing locale that matches closely with your needs</li>
+ * <li>Use this as your base class. Use Y.DataType.Date.Locale["en"] if nothing
+ * matches.</li>
+ * <li>Create your own class as an extension of the base class using
+ * Y.merge, and add your own localisations where needed.</li>
+ * </ol>
+ * See the Y.DataType.Date.Locale["en-US"] and Y.DataType.Date.Locale["en-GB"]
+ * classes which extend Y.DataType.Date.Locale["en"].
+ *
+ * For example, to implement locales for French french and Canadian french,
+ * we would do the following:
+ * <ol>
+ * <li>For French french, we have no existing similar locale, so use
+ * Y.DataType.Date.Locale["en"] as the base, and extend it:
+ * <pre>
+ * Y.DataType.Date.Locale["fr"] = Y.merge(Y.DataType.Date.Locale, {
+ * a: ["dim", "lun", "mar", "mer", "jeu", "ven", "sam"],
+ * A: ["dimanche", "lundi", "mardi", "mercredi", "jeudi", "vendredi", "samedi"],
+ * b: ["jan", "fév", "mar", "avr", "mai", "jun", "jui", "aoû", "sep", "oct", "nov", "déc"],
+ * B: ["janvier", "février", "mars", "avril", "mai", "juin", "juillet", "août", "septembre", "octobre", "novembre", "décembre"],
+ * c: "%a %d %b %Y %T %Z",
+ * p: ["", ""],
+ * P: ["", ""],
+ * x: "%d.%m.%Y",
+ * X: "%T"
+ * });
+ * </pre>
+ * </li>
+ * <li>For Canadian french, we start with French french and change the meaning of \%x:
+ * <pre>
+ * Y.DataType.Date.Locale["fr-CA"] = Y.merge(Y.DataType.Date.Locale["fr"], {
+ * x: "%Y-%m-%d"
+ * });
+ * </pre>
+ * </li>
+ * </ol>
+ *
+ * With that, you can use your new locales:
+ * <pre>
+ * var d = new Date("2008/04/22");
+ * Y.DataType.Date.format(d, { format: "%A, %d %B == %x", locale: "fr" });
+ * </pre>
+ * will return:
+ * <pre>
+ * mardi, 22 avril == 22.04.2008
+ * </pre>
+ * And
+ * <pre>
+ * Y.DataType.Date.format(d, {format: "%A, %d %B == %x", locale: "fr-CA" });
+ * </pre>
+ * Will return:
+ * <pre>

+ * The Date.Locale class is a container for all localised date strings
+ * used by Y.DataType.Date. It is used internally, but may be extended
+ * to provide new date localisations.
+ *
+ * To create your own Locale, follow these steps:
+ * <ol>
+ * <li>Find an existing locale that matches closely with your needs</li>
+ * <li>Use this as your base class. Use Y.DataType.Date.Locale["en"] if nothing
+ * matches.</li>
+ * <li>Create your own class as an extension of the base class using
+ * Y.merge, and add your own localisations where needed.</li>
+ * </ol>
+ * See the Y.DataType.Date.Locale["en-US"] and Y.DataType.Date.Locale["en-GB"]
+ * classes which extend Y.DataType.Date.Locale["en"].
+ *
+ * For example, to implement locales for French french and Canadian french,
+ * we would do the following:
+ * <ol>
+ * <li>For French french, we have no existing similar locale, so use
+ * Y.DataType.Date.Locale["en"] as the base, and extend it:
+ * <pre>
+ * Y.DataType.Date.Locale["fr"] = Y.merge(Y.DataType.Date.Locale, {
+ * a: ["dim", "lun", "mar", "mer", "jeu", "ven", "sam"],
+ * A: ["dimanche", "lundi", "mardi", "mercredi", "jeudi", "vendredi", "samedi"],
+ * b: ["jan", "fév", "mar", "avr", "mai", "jun", "jui", "aoû", "sep", "oct", "nov", "déc"],
+ * B: ["janvier", "février", "mars", "avril", "mai", "juin", "juillet", "août", "septembre", "octobre", "novembre", "décembre"],
+ * c: "%a %d %b %Y %T %Z",
+ * p: ["", ""],
+ * P: ["", ""],
+ * x: "%d.%m.%Y",
+ * X: "%T"
+ * });
+ * </pre>
+ * </li>
+ * <li>For Canadian french, we start with French french and change the meaning of \%x:
+ * <pre>
+ * Y.DataType.Date.Locale["fr-CA"] = Y.merge(Y.DataType.Date.Locale["fr"], {
+ * x: "%Y-%m-%d"
+ * });
+ * </pre>
+ * </li>
+ * </ol>
+ *
+ * With that, you can use your new locales:
+ * <pre>
+ * var d = new Date("2008/04/22");
+ * Y.DataType.Date.format(d, { format: "%A, %d %B == %x", locale: "fr" });
+ * </pre>
+ * will return:
+ * <pre>
+ * mardi, 22 avril == 22.04.2008
+ * </pre>
+ * And
+ * <pre>
+ * Y.DataType.Date.format(d, {format: "%A, %d %B == %x", locale: "fr-CA" });
+ * </pre>
+ * Will return:
+ * <pre>

+ * The Date.Locale class is a container for all localised date strings
+ * used by Y.DataType.Date. It is used internally, but may be extended
+ * to provide new date localisations.
+ *
+ * To create your own Locale, follow these steps:
+ * <ol>
+ * <li>Find an existing locale that matches closely with your needs</li>
+ * <li>Use this as your base class. Use Y.DataType.Date.Locale["en"] if nothing
+ * matches.</li>
+ * <li>Create your own class as an extension of the base class using
+ * Y.merge, and add your own localisations where needed.</li>
+ * </ol>
+ * See the Y.DataType.Date.Locale["en-US"] and Y.DataType.Date.Locale["en-GB"]
+ * classes which extend Y.DataType.Date.Locale["en"].
+ *
+ * For example, to implement locales for French french and Canadian french,
+ * we would do the following:
+ * <ol>
+ * <li>For French french, we have no existing similar locale, so use
+ * Y.DataType.Date.Locale["en"] as the base, and extend it:
+ * <pre>
+ * Y.DataType.Date.Locale["fr"] = Y.merge(Y.DataType.Date.Locale, {
+ * a: ["dim", "lun", "mar", "mer", "jeu", "ven", "sam"],
+ * A: ["dimanche", "lundi", "mardi", "mercredi", "jeudi", "vendredi", "samedi"],
+ * b: ["jan", "fév", "mar", "avr", "mai", "jun", "jui", "aoû", "sep", "oct", "nov", "déc"],
+ * B: ["janvier", "février", "mars", "avril", "mai", "juin", "juillet", "août", "septembre", "octobre", "novembre", "décembre"],
+ * c: "%a %d %b %Y %T %Z",
+ * p: ["", ""],
+ * P: ["", ""],
+ * x: "%d.%m.%Y",
+ * X: "%T"
+ * });
+ * </pre>
+ * </li>
+ * <li>For Canadian french, we start with French french and change the meaning of \%x:
+ * <pre>
+ * Y.DataType.Date.Locale["fr-CA"] = Y.merge(Y.DataType.Date.Locale["fr"], {
+ * x: "%Y-%m-%d"
+ * });
+ * </pre>
+ * </li>
+ * </ol>
+ *
+ * With that, you can use your new locales:
+ * <pre>
+ * var d = new Date("2008/04/22");
+ * Y.DataType.Date.format(d, { format: "%A, %d %B == %x", locale: "fr" });
+ * </pre>
+ * will return:
+ * <pre>
+ * mardi, 22 avril == 22.04.2008
+ * </pre>
+ * And
+ * <pre>
+ * Y.DataType.Date.format(d, {format: "%A, %d %B == %x", locale: "fr-CA" });
+ * </pre>
+ * Will return:

+ * service a specific request for additional information about subscribing
+ * to that type of event.
+ *
+ * <ul>

+ * <li>The type of the event</li>
+ * <li>The callback to execute</li>
+ * <li>An optional context object</li>
+ * <li>0..n additional arguments to supply the callback.</li>
+ * </ul>
+ * Example:
+ * <code>Y.on('domready', function() { // start work });</code>
+ * </li>
+ * <li>DOM events. These are moments reported by the browser related
+ * to browser functionality and user interaction.
+ * This type of event is delegated to <code>Event</code>'s
+ * <code>attach</code> method.
+ * <ul>
+ * <li>The type of the event</li>
+ * <li>The callback to execute</li>
+ * <li>The specification for the Node(s) to attach the listener
+ * to. This can be a selector, collections, or Node/Element
+ * refereces.</li>
+ * <li>An optional context object</li>
+ * <li>0..n additional arguments to supply the callback.</li>
+ * </ul>
+ * Example:
+ * <code>Y.on('click', function(e) { // something was clicked }, '#someelement');</code>
+ * </li>
+ * <li>Function events. These events can be used to react before or after a
+ * function is executed. This type of event is delegated to <code>Event.Do</code>'s
+ * <code>before</code> method.
+ * <ul>
+ * <li>The callback to execute</li>
+ * <li>The object that has the function that will be listened for.</li>

+ * Example <code>Y.on(function(arg1, arg2, etc) { // obj.methodname was executed }, obj 'methodname');</code>
+ * </li>
+ * </ul>

+/**
+ * <code>YUI</code>'s <code>on</code> method is a unified interface for subscribing to
+ * most events exposed by YUI. This includes custom events, DOM events, and
+ * function events. <code>detach</code> is also provided to remove listeners
+ * serviced by this function.
+ *
+ * The signature that <code>on</code> accepts varies depending on the type
+ * of event being consumed. Refer to the specific methods that will
+ * service a specific request for additional information about subscribing
+ * to that type of event.
+ *
+ * <ul>
+ * <li>Custom events. These events are defined by various
+ * modules in the library. This type of event is delegated to
+ * <code>EventTarget</code>'s <code>on</code> method.
+ * <ul>
+ * <li>The type of the event</li>
+ * <li>The callback to execute</li>
+ * <li>An optional context object</li>
+ * <li>0..n additional arguments to supply the callback.</li>
+ * </ul>
+ * Example:
+ * <code>Y.on('domready', function() { // start work });</code>
+ * </li>
+ * <li>DOM events. These are moments reported by the browser related
+ * to browser functionality and user interaction.
+ * This type of event is delegated to <code>Event</code>'s
+ * <code>attach</code> method.
+ * <ul>
+ * <li>The type of the event</li>
+ * <li>The callback to execute</li>
+ * <li>The specification for the Node(s) to attach the listener
+ * to. This can be a selector, collections, or Node/Element
+ * refereces.</li>
+ * <li>An optional context object</li>
+ * <li>0..n additional arguments to supply the callback.</li>
+ * </ul>
+ * Example:
+ * <code>Y.on('click', function(e) { // something was clicked }, '#someelement');</code>
+ * </li>
+ * <li>Function events. These events can be used to react before or after a
+ * function is executed. This type of event is delegated to <code>Event.Do</code>'s
+ * <code>before</code> method.
+ * <ul>
+ * <li>The callback to execute</li>
+ * <li>The object that has the function that will be listened for.</li>
+ * <li>The name of the function to listen for.</li>
+ * <li>An optional context object</li>
+ * <li>0..n additional arguments to supply the callback.</li>
+ * </ul>
+ * Example <code>Y.on(function(arg1, arg2, etc) { // obj.methodname was executed }, obj 'methodname');</code>
+ * </li>
+ * </ul>
+ *
+ * <code>on</code> corresponds to the moment before any default behavior of
+ * the event. <code>after</code> works the same way, but these listeners
+ * execute after the event's default behavior. <code>before</code> is an
+ * alias for <code>on</code>.
+ *
+ * @method on
+ * @param type** event type (this parameter does not apply for function events)
+ * @param fn the callback
+ * @param target** a descriptor for the target (applies to custom events only).
+ * For function events, this is the object that contains the function to
+ * execute.
+ * @param extra** 0..n Extra information a particular event may need. These
+ * will be documented with the event. In the case of function events, this
+ * is the name of the function to execute on the host. In the case of
+ * delegate listeners, this is the event delegation specification.
+ * @param context optionally change the value of 'this' in the callback
+ * @param args* 0..n additional arguments to pass to the callback.
+ * @return the event target or a detach handle per 'chain' config
+ * @for YUI
+ */
+
+/**
+ * after() is a unified interface for subscribing to
+ * most events exposed by YUI. This includes custom events,
+ * DOM events, and AOP events. This works the same way as
+ * the on() function, only it operates after any default
+ * behavior for the event has executed. @see <code>on</code> for more

+ * <ul>
+ * <li>The type of the event</li>
+ * <li>The callback to execute</li>
+ * <li>The specification for the Node(s) to attach the listener

+ * not defined, the default value will be GET.
+ *
+ * data: This is the name-value string that will be sent as the transaction
+ * data. If the request is HTTP GET, the data become part of
+ * querystring. If HTTP POST, the data are sent in the message body.
+ *
+ * xdr: Defines the transport to be used for cross-domain requests. By
+ * setting this property, the transaction will use the specified
+ * transport instead of XMLHttpRequest. Currently, the only alternate
+ * transport supported is Flash (e.g., { xdr: 'flash' }).
+ *
+ * form: This is a defined object used to process HTML form as data. The
+ * properties are:
+ * {
+ * id: object, //HTML form object or id of HTML form
+ * useDisabled: boolean, //Allow disabled HTML form field values
+ * to be sent as part of the data.
+ * }
+ *
+ * on: This is a defined object used to create and handle specific
+ * events during a transaction lifecycle. These events will fire in
+ * addition to the global io events. The events are:
+ * start - This event is fired when a request is sent to a resource.
+ * complete - This event fires when the transaction is complete.
+ * success - This event fires when the response status resolves to
+ * HTTP 2xx.
+ * failure - This event fires when the response status resolves to
+ * HTTP 4xx, 5xx; and, for all transaction exceptions,
+ * including aborted transactions and transaction timeouts.
+ * end - This even is fired at the conclusion of the transaction
+ * lifecycle, after a success or failure resolution.
+ *
+ * The properties are:
+ * {
+ * start: function(id, args){},
+ * complete: function(id, responseobject, args){},
+ * success: function(id, responseobject, args){},
+ * failure: function(id, responseobject, args){},
+ * end: function(id, args){}
+ * }
+ * Each property can reference a function or be written as an
+ * inline function.
+ *
+ * context: Object reference for an event handler when it is implemented
+ * as a method of a base object. Defining "context" will preserve
+ * the proper reference of "this" used in the event handler.
+ * headers: This is a defined object of client headers, as many as.
+ * desired for the transaction. These headers are sentThe object
+ * pattern is:
+ * {
+ * header: value
+ * }
+ *
+ * timeout: This value, defined as milliseconds, is a time threshold for the
+ * transaction. When this threshold is reached, and the transaction's
+ * Complete event has not yet fired, the transaction will be aborted.
+ * arguments: Object, array, string, or number passed to all registered
+ * event handlers. This value is available as the second
+ * argument in the "start" and "abort" event handlers; and, it is
+ * the third argument in the "complete", "success", and "failure"

+ * transport instead of XMLHttpRequest. Currently, the only alternate
+ * transport supported is Flash (e.g., { xdr: 'flash' }).
+ *
+ * form: This is a defined object used to process HTML form as data. The
+ * properties are:
+ * {
+ * id: object, //HTML form object or id of HTML form
+ * useDisabled: boolean, //Allow disabled HTML form field values
+ * to be sent as part of the data.
+ * }
+ *
+ * on: This is a defined object used to create and handle specific
+ * events during a transaction lifecycle. These events will fire in
+ * addition to the global io events. The events are:
+ * start - This event is fired when a request is sent to a resource.
+ * complete - This event fires when the transaction is complete.
+ * success - This event fires when the response status resolves to
+ * HTTP 2xx.
+ * failure - This event fires when the response status resolves to
+ * HTTP 4xx, 5xx; and, for all transaction exceptions,
+ * including aborted transactions and transaction timeouts.
+ * end - This even is fired at the conclusion of the transaction
+ * lifecycle, after a success or failure resolution.
+ *
+ * The properties are:
+ * {
+ * start: function(id, args){},
+ * complete: function(id, responseobject, args){},
+ * success: function(id, responseobject, args){},
+ * failure: function(id, responseobject, args){},
+ * end: function(id, args){}
+ * }
+ * Each property can reference a function or be written as an
+ * inline function.
+ *
+ * context: Object reference for an event handler when it is implemented
+ * as a method of a base object. Defining "context" will preserve
+ * the proper reference of "this" used in the event handler.
+ * headers: This is a defined object of client headers, as many as.
+ * desired for the transaction. These headers are sentThe object
+ * pattern is:
+ * {
+ * header: value
+ * }
+ *
+ * timeout: This value, defined as milliseconds, is a time threshold for the
+ * transaction. When this threshold is reached, and the transaction's
+ * Complete event has not yet fired, the transaction will be aborted.
+ * arguments: Object, array, string, or number passed to all registered
+ * event handlers. This value is available as the second

+ * <li>filter:
+ *
+ * A filter to apply to result urls. This filter will modify the default

+ * This option will automatically include the Logger widget</dd>
+ * <dt>RAW</dt>
+ * <dd>Selects the non-minified version of the library (e.g., event.js).</dd>
+ * </dl>
+ * You can also define a custom filter, which must be an object literal
+ * containing a search expression and a replace string:
+ * <pre>
+ * myFilter: {
+ * 'searchExp': "-min\\.js",
+ * 'replaceStr': "-debug.js"

+ * <li>ignore:
+ * A list of modules that should never be dynamically loaded</li>
+ * <li>force:
+ * A list of modules that should always be loaded when required, even if already present on the page</li>
+ * <li>insertBefore:
+ * Node or id for a node that should be used as the insertion point for new nodes</li>
+ * <li>charset:
+ * charset for dynamic nodes (deprecated, use jsAttributes or cssAttributes)</li>
+ * <li>jsAttributes: object literal containing attributes to add to script nodes</li>
+ * <li>cssAttributes: object literal containing attributes to add to link nodes</li>
+ * <li>timeout:
+ * number of milliseconds before a timeout occurs when dynamically loading nodes. in not set, there is no timeout</li>
+ * <li>context:
+ * execution context for all callbacks</li>
+ * <li>onSuccess:
+ * callback for the 'success' event</li>
+ * <li>onFailure: callback for the 'failure' event</li>
+ * <li>onCSS: callback for the 'CSSComplete' event. When loading YUI components with CSS
+ * the CSS is loaded first, then the script. This provides a moment you can tie into to improve
+ * the presentation of the page while the script is loading.</li>
+ * <li>onTimeout:
+ * callback for the 'timeout' event</li>
+ * <li>onProgress:
+ * callback executed each time a script or css file is loaded</li>

+* <p>The Focus Manager Node Plugin makes it easy to manage focus among
+* a Node's descendants. Primarily intended to help with widget development,
+* the Focus Manager Node Plugin can be used to improve the keyboard
+* accessibility of widgets.</p>
+*
+* <p>
+* When designing widgets that manage a set of descendant controls (i.e. buttons
+* in a toolbar, tabs in a tablist, menuitems in a menu, etc.) it is important to
+* limit the number of descendants in the browser's default tab flow. The fewer
+* number of descendants in the default tab flow, the easier it is for keyboard
+* users to navigate between widgets by pressing the tab key. When a widget has
+* focus it should provide a set of shortcut keys (typically the arrow keys)
+* to move focus among its descendants.
+* </p>
+*
+* <p>
+* To this end, the Focus Manager Node Plugin makes it easy to define a Node's
+* focusable descendants, define which descendant should be in the default tab
+* flow, and define the keys that move focus among each descendant.
+* Additionally, as the CSS
+* <a href="http://www.w3.org/TR/CSS21/selector.html#x38"><code>:focus</code></a>
+* pseudo class is not supported on all elements in all
+* <a href="http://developer.yahoo.com/yui/articles/gbs/">A-Grade browsers</a>,
+* the Focus Manager Node Plugin provides an easy, cross-browser means of
+* styling focus.
+* </p>

+* <p>The Focus Manager Node Plugin makes it easy to manage focus among
+* a Node's descendants. Primarily intended to help with widget development,
+* the Focus Manager Node Plugin can be used to improve the keyboard
+* accessibility of widgets.</p>
+*
+* <p>
+* When designing widgets that manage a set of descendant controls (i.e. buttons
+* in a toolbar, tabs in a tablist, menuitems in a menu, etc.) it is important to
+* limit the number of descendants in the browser's default tab flow. The fewer
+* number of descendants in the default tab flow, the easier it is for keyboard
+* users to navigate between widgets by pressing the tab key. When a widget has
+* focus it should provide a set of shortcut keys (typically the arrow keys)
+* to move focus among its descendants.
+* </p>
+*
+* <p>
+* To this end, the Focus Manager Node Plugin makes it easy to define a Node's
+* focusable descendants, define which descendant should be in the default tab
+* flow, and define the keys that move focus among each descendant.
+* Additionally, as the CSS
+* <a href="http://www.w3.org/TR/CSS21/selector.html#x38"><code>:focus</code></a>
+* pseudo class is not supported on all elements in all
+* <a href="http://developer.yahoo.com/yui/articles/gbs/">A-Grade browsers</a>,
+* the Focus Manager Node Plugin provides an easy, cross-browser means of
+* styling focus.

+NOTES
+ * Style node must be added to the head element. Safari does not honor styles
+ applied to StyleSheet objects on style nodes in the body.
+ * StyleSheet object is created on the style node when the style node is added
+ to the head element in Firefox 2 (and maybe 3?)
+ * The cssRules collection is replaced after insertRule/deleteRule calls in
+ Safari 3.1. Existing Rules are used in the new collection, so the collection
+ cannot be cached, but the rules can be.
+ * Opera requires that the index be passed with insertRule.
+ * Same-domain restrictions prevent modifying StyleSheet objects attached to
+ link elements with remote href (or "about:blank" or "javascript:false")
+ * Same-domain restrictions prevent reading StyleSheet cssRules/rules
+ collection of link elements with remote href (or "about:blank" or
+ "javascript:false")
+ * Same-domain restrictions result in Safari not populating node.sheet property
+ for link elements with remote href (et.al)
+ * IE names StyleSheet related properties and methods differently (see code)
+ * IE converts tag names to upper case in the Rule's selectorText
+ * IE converts empty string assignment to complex properties to value settings
+ for all child properties. E.g. style.background = '' sets non-'' values on
+ style.backgroundPosition, style.backgroundColor, etc. All else clear
+ style.background and all child properties.
+ * IE assignment style.filter = '' will result in style.cssText == 'FILTER:'
+ * All browsers support Rule.style.cssText as a read/write property, leaving
+ only opacity needing to be accounted for.
+ * Benchmarks of style.property = value vs style.cssText += 'property: value'
+ indicate cssText is slightly slower for single property assignment. For
+ multiple property assignment, cssText speed stays relatively the same where
+ style.property speed decreases linearly by the number of properties set.
+ Exception being Opera 9.27, where style.property is always faster than
+ style.cssText.
+ * Opera 9.5b throws a syntax error when assigning cssText with a syntax error.
+ * Opera 9.5 doesn't honor rule.style.cssText = ''. Previous style persists.
+ You have to remove the rule altogether.
+ * Stylesheet properties set with !important will trump inline style set on an
+ element or in el.style.property.
+ * Creating a worker style collection like document.createElement('p').style;
+ will fail after a time in FF (~5secs of inactivity). Property assignments
+ will not alter the property or cssText. It may be the generated node is
+ garbage collected and the style collection becomes inert (speculation).
+ * IE locks up when attempting to add a rule with a selector including at least
+ characters {[]}~`!@%^&*()+=|? (unescaped) and leading _ or -
+ such as addRule('-foo','{ color: red }') or addRule('._abc','{...}')
+ * IE's addRule doesn't support comma separated selectors such as
+ addRule('.foo, .bar','{..}')
+ * IE throws an error on valid values with leading/trailing white space.
+ * When creating an entire sheet at once, only FF2/3 & Opera allow creating a
+ style node, setting its innerHTML and appending to head.
+ * When creating an entire sheet at once, Safari requires the style node to be
+ created with content in innerHTML of another element.
+ * When creating an entire sheet at once, IE requires the style node content to
+ be set via node.styleSheet.cssText
+ * When creating an entire sheet at once in IE, styleSheet.cssText can't be
+ written until node.type = 'text/css'; is performed.
+ * When creating an entire sheet at once in IE, load-time fork on
+ var styleNode = d.createElement('style'); _method = styleNode.styleSheet ?..
+ fails (falsey). During run-time, the test for .styleSheet works fine
+ * Setting complex properties in cssText will SOMETIMES allow child properties
+ to be unset
+ set unset FF2 FF3 S3.1 IE6 IE7 Op9.27 Op9.5

+NOTES
+ * Style node must be added to the head element. Safari does not honor styles
+ applied to StyleSheet objects on style nodes in the body.
+ * StyleSheet object is created on the style node when the style node is added
+ to the head element in Firefox 2 (and maybe 3?)
+ * The cssRules collection is replaced after insertRule/deleteRule calls in
+ Safari 3.1. Existing Rules are used in the new collection, so the collection
+ cannot be cached, but the rules can be.
+ * Opera requires that the index be passed with insertRule.
+ * Same-domain restrictions prevent modifying StyleSheet objects attached to
+ link elements with remote href (or "about:blank" or "javascript:false")
+ * Same-domain restrictions prevent reading StyleSheet cssRules/rules
+ collection of link elements with remote href (or "about:blank" or
+ "javascript:false")
+ * Same-domain restrictions result in Safari not populating node.sheet property
+ for link elements with remote href (et.al)
+ * IE names StyleSheet related properties and methods differently (see code)
+ * IE converts tag names to upper case in the Rule's selectorText
+ * IE converts empty string assignment to complex properties to value settings
+ for all child properties. E.g. style.background = '' sets non-'' values on
+ style.backgroundPosition, style.backgroundColor, etc. All else clear
+ style.background and all child properties.
+ * IE assignment style.filter = '' will result in style.cssText == 'FILTER:'
+ * All browsers support Rule.style.cssText as a read/write property, leaving
+ only opacity needing to be accounted for.
+ * Benchmarks of style.property = value vs style.cssText += 'property: value'
+ indicate cssText is slightly slower for single property assignment. For
+ multiple property assignment, cssText speed stays relatively the same where
+ style.property speed decreases linearly by the number of properties set.
+ Exception being Opera 9.27, where style.property is always faster than
+ style.cssText.
+ * Opera 9.5b throws a syntax error when assigning cssText with a syntax error.
+ * Opera 9.5 doesn't honor rule.style.cssText = ''. Previous style persists.
+ You have to remove the rule altogether.
+ * Stylesheet properties set with !important will trump inline style set on an
+ element or in el.style.property.
+ * Creating a worker style collection like document.createElement('p').style;
+ will fail after a time in FF (~5secs of inactivity). Property assignments
+ will not alter the property or cssText. It may be the generated node is
+ garbage collected and the style collection becomes inert (speculation).
+ * IE locks up when attempting to add a rule with a selector including at least
+ characters {[]}~`!@%^&*()+=|? (unescaped) and leading _ or -
+ such as addRule('-foo','{ color: red }') or addRule('._abc','{...}')
