Hello!

I have run into an issue with annotation properties and their support
by two popular validators.

Pellet [1] indicates that the following is OWL-Lite/DL, yet WonderWeb
[2] throws a warning due to an "Untyped Individual" and forces
OWL-Full.

      <owl:onProperty rdf:resource="http://test" />
      <owl:minCardinality>1</owl:minCardinality>
    </owl:Restriction>
  </rdfs:subClassOf>
</owl:Class>

<owl:ObjectProperty rdf:about="http://test" />
</rdf:RDF>

Thanks for your time.
