Recall that in RDF/DAML+OIL/OWL classes and other resources
are named by full URIs, so

  http://www.cs.umd.edu/projects/plus/DAML/onts/general1.0.daml#Thing

and

  http://www.w3.org/2002/07/owl#Thing

are different Things.

Any Class is implicitly a subClassOf daml:Thing (but not
necessarily a proper subclass).  One could potentially
equate Entity and daml:Thing using daml:sameClassAs.
