Re: PROPOSAL to close ISSUE-55

It appears to me that ISSUE-55 asks for a solution that eliminates the
differences between rdfs:Class and owl:Class, or a statement as to why
this is not a good idea.  There have already been statements that say
why rdfs:Class and owl:Class are different.

A WG note providing best practices in ontology "repair" by tools (which
could include lots of other "repairs", including, perhaps repairs in OWL
Full ontologies) would be a solution to a different problem, and thus, I
think, should be a different issue.
