Symbols have 1 output element e.g. for -Infinity in Latex this is
    -<Infinity>
        -<output>\infty</output>
    -</Infinity>

Groupings have 2 output elements e.g. -for square brackets in Latex this is
    <BracketsSq>
        -<output1>\left[</output1>
        -<output2>\right]</output2>
    -</BracketsSq>

Matrix in Latex is as -follows:
    <Matrix>
        -<matrixStart>\left( -\begin{array}{ccc}</matrixStart>
        -<rowStart />
        -<elementStart />
        -<elementEnd />
        -<elementSeparator><![CDATA[ & -]]></elementSeparator>
        -<rowEnd> \\ </rowEnd>
        -<rowSeparator />
        -<matrixEnd>\end{array} -\right)</matrixEnd>
    -</Matrix>

The syntax within these tags is used -when converting an expression to that particular format. The actual arguments of -the objects appear in the syntax between each pair of tags. For example consider -½ in Latex format. It has 3 output elements. So the first part will be -\frac{, then the first argument will be appended to the string giving us, -\frac{1, then the 2nd output will be appended, \frac{1}{, then the 2nd -argment, \frac{1}{2 and then the final output, \frac{1}{2}. A similar process -takes place with all the object types of objects, with the argument being -appended between each pair of output elements.

There are various options -that can be set to allow more control over the -output.

Reverse
If you find the arguments -of a binary operator being output in the wrong order for a format, you can -reverse the order of them by setting, reverse=true. An example of this is with -the N-th root in Latex,
    <NthRoot reverse="true" brackets="false">
        -<output1>\sqrt[ -</output1>
        -<output2>]{</output2>
        -<output3>}</output3>
    -</NthRoot>

Argument Order

If you find the arguments of an N-ary Function being output in the wrong -order for a format, you can re-arrange the order of them by setting, -order=#1,#2,#3,...,#n. An example of this is with the Sum in Latex. -Obviously, the default order for this is 0,1,2,3, and it is being -changed to 1,2,3,0.
    <Sum order="1,2,3,0">
        -<output1> \sum_{{</output1>
        -<output2>}={</output2>
        -<output3>}}^{</output3>
        -<output4>}</output4>
        -<output5></output5>
    -</Sum>

AutoBrackets
By default, round -brackets are placed around n-ary operators and binary operators where necessary -to ensure operator precedence is preserved. For presentational formats, such as -Latex this is often unnecessary, so there is the option to turn automatic -placing of brackets on/off. This is set in the element that specifies the name -of the format. An example of this is shown for -Latex,

<name AutoBrackets="false">Latex</name>

Brackets on Functions
Brackets -are added by default around the argument of a function. For example Sine in -Latex is,
    <Sine>
        -<output1>\sin -</output1>
        <output2 -/>
    </Sine>

Brackets are -automatically added after the \sin and after the 2nd output, resulting in -"\sin(arg)". This is often the desired result but if you need to turn the -brackets off, they can be set for each individual function. An example of -turning them off is shown here for Square root in -Latex,
    <SquareRoot brackets="false">
        -<output1>\sqrt{</output1>
        -<output2>}</output2>
    -</SquareRoot>

Initial
As well as the structured -number of output elements for each type of object, there is the option of having -an initial element. The data in this element is added to the string before any -other output element is. An example of its use for describing multiplication in -MathML Content is shown below.
    <Add>
        -<initial><times/></initial>
        -<output</output>
    -</Add>

a x b x c would then be converted -to,
    -<times/>
        -<ci>a</ci>
        -<ci>b</ci>
        -<ci>c</ci>

Final

N-ary operators can also have an optional 'final' -element for adding data after everything else. An example of this is with Union -in Maxima.

    <Union>
        -<initial>union(</initial>
        -<output>,</output>
        -<final>)</final>
    -</Union>
