@role or @class used to be in discussion for 
syntactic sugar of doing a shorthand for 'rdf:type'.

IIRC we have not yet finally resolved this issue but we
have a non-binding resolution [1] to call the magic attribute
'instanceof'.

Unfortunately none of the RDFa extractors out there 
currently supports 'instanceof' AFAIK. 
Please, people, proof that I'm wrong ;)

And again, just for clarity: No, it is NOT correct to
use @role or @class, though the available implementations 
might eat it - *currently*. 

Cheers,
