I don't really understand what the problem you are describing is... could 
you provide some examples? (In particular, it's not clear to me why RDFa 
would be easier to handle than HTML class attributes.)

Implementation experience such as yours is very useful, the more you can 
tell us about your experiences the better (especially concrete examples).
