The Semantics document currently uses rdfs:Literal as the class of all
literals.   However, it is no longer the case that the class extension
rdfs:Literal is related at all to the set of all literals.

I think that I can fix the Semantics document (contrary to what I had just
thought) to eliminate the use of rdfs:Literal.  This is not ideal, I think,
and I would much prefer to use rdfs:Literal.

Separately, however, I believe there are serious bugs in the RDF MT related
to rdfs:Literal, which I mentioned to RDF Core.  These need to be fixed
before WebOnt gets to last call, as the Semantics document normatively
depends on the RDF model theory.
