Module LaTeXML-math in E. Schema in LaTeXML The Manual

The math module defines LaTeXML's internal representation of mathematical content, including the basic math container Math. This element is considered inline, as it will be contained within some other block-level element, eg. equation for display-math.

|= Math

This class defines the content of the Math element. Additionally, it could contain MathML or OpenMath, after postprocessing.

==XMath

These elements comprise the internal math representation, being the content of the XMath element.

Outer container for all math. This holds the internal XMath representation, as well as image data and other representations.

attributes:

Common.attributes, Imageable.attributes

included

mode

display or inline mode.

= (`display' | `inline')

tex

reconstruction of the TeX that generated the math.

content-tex

more semantic version of tex.

text

a textified representation of the math.

content: Math.class*

== Attributes:

role: The role that this item plays in the Grammar.
open: an open delimiter to enclose the object;
close: an close delimiter to enclose the object;
argopen: an open delimiter to enclose the argument list, when this token is applied to arguments with XMApp.
argclose: a close delimiter to enclose the argument list, when this token is applied to arguments with XMApp.
separators: characters to separate arguments, when this token is applied to arguments with XMApp. Can be multiple characters for different argument positions; the last character is repeated if there aren't enough.
punctuation: trailing (presumably non-semantic) punctuation.
possibleFunction: an annotation placed by the parser when it suspects this token may be used as a function.

Internal representation of mathematics.

attributes: Common.attributes

content: XMath.class*

General mathematical token.

attributes:

Common.attributes, XMath.attributes, ID.attributes: included
name: The name of the token, typically the control sequence that created it.
meaning: A more semantic name corresponding to the intended meaning, such as the OpenMath name.
omcd: The OpenMath CD for which meaning is a symbol.
style: Various random styling information. NOTE This needs to be made consistent.
font: The font, size a used for the symbol.
size: The size for the symbol, not presumed to be meaningful(?)
color: The color (CSS format) for the symbol, not presumed to be meaningful(?)
scriptpos: An encoding of the position of this token as a sub/superscript, used to handle aligned and nested scripts, both pre and post. It is a concatenation of (pre|mid|post), which indicates the horizontal positioning of the script with relation to it's base, and a counter indicating the level. These are used to position the scripts, and to pair up aligned sub- and superscripts. NOTE: Clarify where this appears: token, base, script operator, apply?
thickness: NOTE: How is this used?

content: #PCDATA*

Generalized application of a function, operator, whatever (the first child) to arguments (the remaining children). The attributes are a subset of those for XMTok.

attributes:

Common.attributes, XMath.attributes, ID.attributes: included
name: The name of the token, typically the control sequence that created it.
meaning: A more semantic name corresponding to the intended meaning, such as the OpenMath name.
scriptpos: An encoding of the position of this token as a sub/superscript, used to handle aligned and nested scripts, both pre and post.

content: XMath.class*

Parallel markup of content (first child) and presentation (second child) of a mathematical object. Typically, the arguments are shared between the two branches: they appear in the content branch, with id's, and XMRef is used in the presentation branch

attributes: Common.attributes, XMath.attributes, ID.attributes

content: XMath.class XMath.class

Various spacing items, generally ignored in parsing. The attributes are a subset of those for XMTok.

attributes:

Common.attributes, XMath.attributes, ID.attributes: included
name
meaning
style

content: empty

Text appearing within math.

attributes: Common.attributes, XMath.attributes, ID.attributes

content: (#PCDATA | Inline.class | Misc.class)*

Wrapper for a sequence of tokens used to assert the role of the contents in its parent. This element generally disappears after parsing. The attributes are a subset of those for XMTok.

attributes:

Common.attributes, XMath.attributes, ID.attributes: included
name
meaning: A more semantic name corresponding to the intended meaning, such as the OpenMath name.
style

content: XMath.class*

Wrapper for an argument to a structured macro. It implies that its content can be parsed independently of its parent, and thus generally disappears after parsing.
