I can give _a_ clarification: this seems just like Pat and Guha's most
recent "reserved triples" proposal to RDFCore, whereby these triples are
considered "reserved for syntax" by OWL.

In such case, indeed, the entailments licensed by the RDF MT are not the
same as those licensed by OWL which underscores the importance of something
like Lbase to 'coordinate' between the RDF and OWL MTs -- well this is my
impression.

Jeremy, if my interpretation (sic :-) is correct, then perhaps we find
ourselves in agreement :-))
