`<mathml>`

Use the <mathml> element to contain content that contributes to a semantic equation. Such content includes MathML elements, references to MathML elements held in separate, non-DITA documents, <data>, or <data-about> elements.

The <mathml> element is not intended to represent a semantic equation, only content that contributes to a semantic equation. Use the equation domain elements or their equivalent to represent equations semantically, for example, to enable numbering of equations.

The MathML markup must have a root element of <math> within the MathML namespace: "http://www.w3.org/1998/Math/MathML".
