Fair enough, but is there a case for doing it for accessibility reasons?  What is 
needed is a clean way to apply relative size attributes to bits of text... pardon me 
for jumping in to the discussion late,  but do we not have this now?  If markup is 
the only means we have at the moment then my assumption from an accessibility 
perspective is that markup is the only accessible sizing mechanism we have.

This sounds dangerous from an accessibility POV as well...
