Summary: changes to RDFS are in charter for RDF Core WG and do not need to

My understanding of the issue is that it is to do with the use of classes of
classes and classes of properties.

As far as I can tell RDF M&S was silent on these, and RDFS did not reach
full rec because it was not compatible (in domain & range) with the DL
approach. If/when we have uncovered further incompatibilities between RDFS
and the DL approach (in say the meta-model) these would strike me as being
*in charter* for the current RDF working group, and not an RDF2 issue.

If what is required is syntactic changes or other semantic changes to better
accomodate OWL then I agree with Dan.
