Many thanks for webont's efforts in reviewing the RDFCore specs.

I think this is the same issue as


I have added webont as a co-submitter.

I think this is the same comment as


Again I have recorded webont as a co-submitter.

This issue is recorded as


As before, I have recorded webont as a co-submitter.

I see not comments from Raphael.

RDFCore will consider this and respond in due course.

This has been recorded as


As webont did not reach consensus, I have not added webont as a 
co-submitter, but we are aware that Ian is not alone in his concern.

Many thanks to Herman, Peter and others who are helping to improve the 
semantics document.  I believe no specific action is needed here by RDFCore 
other than to respond to the comments made by Herman and Peter.

Thanks for all your efforts Jim.  If you have any concerns, let me know.
