Actually this is my fault for not being specific.  I'm not provposing
removing owl:sameClassAs from OWL.  I'm proposing removing 
owl:subClassOf owl:samePropertyOf rdfs:subClassOf .
and 11 other, similar triples from OWL.  These triples all come from the
last section of daml+oil.daml (or whatever it was called).

I'll resubmit the ISSUE.
