<label> Label (of an Equation, Figure, Reference, etc.)
Number and/or prefix word placed at the beginning of display elements (for example,
equation, statement, figure).
Usage/Remarks
As an example, a label placed at the beginning of an equation (<disp-formula>) could be a number such as <label>Equation 3.</label>, <label>(3)</label>, or <label>3.</label>. A label before a statement such as a Proof or Lemma, could be a word such as <label>Proof</label> or <label>Hypothesis</label>.
Accessibility
Sometimes a <label> needs to be pronounced in a way that is not reflected in its content or its tagging.
The @alt attribute can be used to record the pronunciation for screen readers and other accessibility
devices. For example, a cross-reference to a figure might be pronounced as “Figure
3”.
<label alt="figure 3">Fig III.</label>
