It's not really possible, since the SGML approach is to keep the content
and the formatting apart.
One approach is to abuse an attribute of an element. For example, a
back end processor might convert
<emphasis>something</>
into italic, and
<emphasis role="bf">something</>
into a bold face. But this doesn't really scale, and (of course) it's up to
the back end processor (or DSSSL stylesheet) to know that the 'bf' value of
a 'role' attribute means that it should be rendered in a bold face.
I welcome corrections from anyone else reading this, but that's my take on
the issue.
