Re: pfps-04 [RDF entailment rules not yet complete]

I believe that the rules for rdf entailments are still incomplete in 
RDF Semantics (Editors [sic] Draft of July 27).

For example, consider the RDF graph

	ex:foo ex:bar "<ex/>"^^rdf:XMLLiteral .

I believe that this graph rdf-entails

	ex:foo ex:bar "<ex></ex>"^^rdf:XMLLiteral .

but that this cannot be derived from the RDF entailment rules.
