LaTeXML HTML Attribute Contract +Common attributes with class removed.

+ + +

LaTeXML’s XML schema keeps semantic membership in element names such +as section, para, equation, tabular, and text. The HTML transform +moves that information into deterministic class tokens, normally +beginning with ”ltx_” plus the original XML element local name. These +helpers keep the stock HTML attribute vocabulary, but require the +LaTeXML class token that carries the profile semantics. + + ltx.attrs.no-class + schema pattern +
