Re: bug in RDF model theory having to do with rdfs:subClassOf and rdfs:subPropertyOf

I was wrong in my initial speculation that making the semantic constraint for
rdfs:subClassOf an iff constraint would not have RDFS-observable
consequences.

If the semantic constraint for rdfs:subClassOf is changed to an iff
constraint then

	rdf:type rdfs:domain foo .

would entail

	rdfs:Resource rdfs:subClassOf foo.
