RE: Constraining Collections?

Yeah, that seems cleaner (and less likely to freak out dls?).

rss:Channel rdfs:subClassOf 
 [ a owl:Restriction;
  owl:onProperty rss:items;
  owl:allValuesFrom 
   [rdfs:subClassOf rdf:Seq,
    [a owl:Restriction;
	owl:onProperty rdfs:member;
      owl:allValuesFrom rss:item
    ]
   ]
  ].
