Jim: I would like to emphasize that none of the suggestions that I 
made in this thread was intended to change the design.  The purpose was
to make the changes needed to make S&AS consistent with the RDF Semantics
document, as the title of the thread suggests.
There is one case where I proposed a change which I expected to leave
the semantics the same, in the same way as a similar change in the
RDF semantics did, but which Peter discovered would
change the design of OWL Full, and when this change was undone I said:
>>That this would change the semantics, is indeed an objective
>>reason for undoing the change.
>>I can live with the current version of this definition.

There seem to be two misunderstandings in the discussion of yesterday
that may lead to the impression that changes to the design were discussed:
I based my understanding of the design of OWL semantics on S&AS, but 
my statements based on this led Peter and Jeremy to say that I was
making proposals to change the design.  The problem that seems to arise is
that, with respect to XMLLiteral, the design of the OWL semantics
does not yet seem to be completely correctly represented in S&AS,
see my next message.

For S&AS, this seems to be an issue.  See my next mail.
