Display Formula
Capture block mathematical content in a <disp-formula>
element.
When in the body of an article <disp-formula>
elements must only
be included as a child of <p>
.
Each <disp-formula>
element may optionally have a
<label>
child elements if present in the source.
Each <disp-formula>
element must contain one each of
<tex-math>
, <mml:math>
and
<graphic>
elements; containing the LaTeX, MathML and
graphical versions of the equation respectively.
