<disp-formula>
Formula, Display
Mathematical equation, expression, or formula that is to be displayed as a block
(callout) within the narrative flow.
Remarks
A <disp-formula> need not be a “formula” in the strict mathematical sense, but can be used for any mathematical expression or equation.
This element may contain the actual characters that make up an equation or formula
or a graphic that contains the formula. Thus, the mathematics can be expressed as ASCII
characters; MathML, TeX, or LaTeX expressions; or as a graphic or series of
graphics.
A display equation may numbered, using automatic numbering or by storing the number in a <label> element.
