Imports/Validation nasty case

I came across the following in an example that somebody was trying to 
validate.

I find at http://foo.bar/ontology.owl the following:

<rdf:RDF ..usual stuff..>
<owl:Ontology rdf:about="">
   <owl:imports rdf:resource="http://ontos-r-us.com/ontologies/stuff.owl"/>
</owl:Ontology>
</rdf:RDF>

At http://ontos-r-us.com/ontologies/stuff.owl we find:

<rdf:RDF ..usual stuff..
      xml:base="http://ontos-r-us.com/ontologies/stuff">

<owl:Ontology rdf:about=""/>
</rdf:RDF>

Now we discover that http://foo.bar/ontology.owl is *not* Lite as there 
is an ontology triple that has an untyped object. I guess this is 
probably something that's going to cause problems as servers do content 
negotiation....

Should we put a test case in for this?
