TITLE:		should OWL provide synonyms for RDF and RDFS objects
DESCRIPTION:    The DAML+OIL official definition contains 12 sameXxxAs
		statements (see below) that provide daml: synonyms for 12 resources
		that are part of RDF or RDFS.  This is probably a bad idea
		that should not be repeated in OWL as it can lead to
		confusion as to what comes from where, particularly as not
		all RDF and RDFS built-in resources are so treated, and at
		least one ``local name'', Class, is used in both RDFS and
		OWL. 

		The 12 DAML+OIL statements in question are 

<rdf:Property rdf:ID="subPropertyOf">
  <samePropertyAs  rdf:resource="http://www.w3.org/2000/01/rdf-schema#subPropertyOf"/>
</rdf:Property>

<rdfs:Class rdf:ID="Class">
  <sameClassAs rdf:resource="http://www.w3.org/2000/01/rdf-schema#Class"/>
