Can we ask WebOnt to add a pair of test cases justifying the difference? I wonder whether a consensus comment might be something like: [[ The RDF Core WG failed to persuade itself that there were, or were not, good reasons for the distinction between rdfs:Class and owl:Class. Can two test cases be added to the OWL Test Cases such that: - the first uses owl:Class - the second uses rdfs:Class and they demonstrate the difference between the two concepts? We note that while, for instance, owl:DatatypeProperty, bears no relationship to owl:Class in the direct semantics, or in OWL DL, that the only way of exploring this difference is through a triple such as: owl:DatatypeProperty rdf:type owl:Class . which, like the triple, owl:DatatypeProperty rdf:type rdfs:Class . is only syntactically permitted in OWL Full, where the two triples are equivalent. ]] Some might want a "If this is not possible ..." clause at the end.
