Hi,

I like the idea of being able to do this (very sensible on the  
semantic web), but doesn't this interact with the imports section as  
well? Unless of course by 'import' you meant 'load'...

An RDF/XML file containing only PropertyAssertions does not contain an  
OntologyURI or VersionURI (as there is no owl:Ontology element), so it  
cannot be imported from another ontology.

PS Trackbot, this is related to ISSUE-21
