Roll your eyes all you want but when you get bored, perhaps you'd like 
to try thinking about the relative difficulty of the two tasks instead 
:-) For many widgets it is entirely obvious what their role attribute 
should be (if it walks like a duck and quacks like a duck it's a duck). 
So adding this information to the semantic layer (i.e. not CSS) is easy. 
Furthermore, people who make common widget toolkits can add 
accessibility information at the toolkit layer (see e.g. [1]) so authors 
don't need to work very hard.

Indeed there are, I believe, a number of problems with microformats 
associated with their use of the class attribute (e.g. I remember a 
discussion some time ago in which it turned out that microformats must 
use globally unique classnames)
