I found it easy to read ...

My take is that the semantic web will be weakened if the different layers
unnecessarily take different branches at choices that face them.

Hence, I think we either should:
- follow the RDF model theory
- agree a WG comment about the RDF model theory as to why some other
approach to classes is better

Is there anything fundamentally wrong with the approach taken in the RDF
model theory?

Jeremy


PS: Peter's analysis seemed to indicate that equivalentTo was the only
interesting one of these relationships in the superstrong approach.
