I'd say just toss it into the class name.
The writer could then have a default handler for
anything it doesn't specifically recognize. In
HTML, it would be <span class="unrecognized-role">,
in DocBook maybe <phrase role="unrecognized-role">.
In some other format, it could be just to ignore
the tags and handle the element's content.
