It does mean we're using part of the precious global NCName namespace. There's the possibility of confusion when mixing RDFa-enabled and non-RDFa-enabled XML vocabularies, but I think all our vocabularies are likely to be RDFa-enabled, so that's probably not a problem. > I'm not convinced so-far that there's a case for adding this to RDFa > Core.

Well it was impacting me :-) but that's because I'd chosen to use QNames for attributes, I can revert back to NCNames. > For what it's worth, the latest development version of my RDFa parser > (RDF::RDFa::Parser - this is the parser that powers check.rdfa.info) > does allow for namespaced attributes (though all the attributes have to > reside in the same namespace as each other).

Ooh cool. Thanks for your help! Alan.
