Mike - how about instead of subclasses, we simply invent a "keyword" 
field.  My reason for preferring this is that it then becomes 
extensible - but also because if it will be easier for a tool to scan 
for ontology declarations if it doesn't need to do inferencing to get 

I'd suggest something like

<owl:ontology  owl:level="lite" rdf:about="">
   <owl:imports .../>
   <owl:version .../>

If I've read the new RDF documents correctly, this is legal, clean 
and an easy way to provide that mechanism.
p.s. I can live with the subclassing, just find this somewhat 
preferable as it will make things a little easier for my tool
