I believe that my message was in response to some working in one or more of
the RDF specs that says something like:

1/ An RDF datatype *is* (just like) an XML Schema datatype.
2/ An RDF datatype has only a lexical space, a value space, and a
   lexical-to-value map.

These two statements are contradictory, so something has to give.  I
don't care which something.
