<inline-formula> Formula, Inline

Mathematical equation, expression, or formula that is to be displayed inline. The mathematics itself can be expressed as ASCII characters, as a graphic, or using TeX, LaTeX, or MathML mathematics expressions.

Usage/Remarks

Some print-oriented tag sets use a specific element to indicate “go into math mode or math font here”. While that was not the intended usage of this element, in nearly all cases the text inside such math-changes is a mathematical expression. It would not be incorrect to use this element to mark such material; however, some organizations may find this tagging undesirable as it proliferates “equations”.
Related Elements
For a mathematical equation, expression, or formula which is to displayed as a block (callout), use the <disp-formula> element.
