If default style is roman, then the rest is up to author, (s)he can either
use LaTeX like math-italic approach and mark roman characters appropriately,
or vise-versa (mark variables apropriately).

But this concept is not part of HTML.

What else can be done?

In this case no HTML markup is necessary at all,
one can use LaTeX-like input and let script to do the rest of job.
