Re: Schism in the Semantic Web community.

We had a number of numeric terms that we could not store as RDF/XML  
'in their native form' the way we wanted, so they were published with  
an underscore in front and a prefLabel attribute. Don't know if that's  
the question you asked, but addresses the point of whether people  
really run into this. I agree it's a problem with RDF/XML and  
shouldn't be worked around in OWL.
