Of course!  That's open source in action ;)

You might also find that the intermediate representation for CSS 
expressions could be turned into a Genshi filter/selector/whatever-it-is 
of some sort.  Currently there's the objects in cssselect with .xpath() 
methods -- you could augment them with a .match(markup_obj) method or 
something along those lines.  Anyway, it might be a useful way to speed 
it up later.
