188.8.131.52 Equation domain elements
The elements in the equation domain enable authors to clearly distinguish equations from other type of content. These markup distinctions can enable formatting distinctions, numbering of equations, and more. This domain can be used independently of the MathML domain.
The equation domain elements do not attempt to satisfy all possible requirements for representing equations semantically. More sophisticated users of equations might need to further specialize from these elements or provide an alternative vocabulary for semantic equations.
