OK.  I should not have modified the mapping rules, and have now taken
rdfs:comment and rdfs:label out.  If you want any of them in, please raise
an issue.

Agreed, and thus I have taken rdfs:comment and rdfs:label out.  Would you
like me to take out the other changes I just made?

I believe that the ball is in your court, as all three of these features
appear in an approved working draft.  dataRange has been in the abstract
syntax from the beginning.  The abstract syntax has also never had XML
Literals.  The exclusion of rdfs:comment, etc., was a consequence of the
incorporation of the OWL semantics into the document, as the list of
excluded URI references was found to be incomplete.

I believe that the only substantive differences are in the augmentations of
what counts as an OWL DL RDF graph, most of which have been requested by you.

Feel free.
