That's what I gathered as well, but this raises a couple of (maybe not  
so very important) issues:
* Are these ontology annotations 'mere' annotations? Or do we think  
they should have semantics... (mustUnderstand)
* The mapping from RDF should at least translate the OWL 1.0 ontology  
properties to annotations (by the way, it seems that at the moment the  
mapping does not translate an RDF owl:Ontology element at all)
* Anyone (i.e. me) looking for these properties in the new spec will  
be surprised by their absence.

Best,
