Agreed. subClassOf is one of the synonymed `local names'.

Class is not one of the synonymed(?) `local names', so I think that Mike's
proposed issue is somewhat different.  He is asking whether both owl:Class
and rdfs:Class are needed.  I am asking whether owl:subClassOf should be a
built-in OWL name that is ``the same as'' rdfs:subClassOf.
