Even if it is ugly, I think we should additionally have the
"owl:distinctMembers" version of owl:AllDifferent. We have it in both the
reverse RDF Mapping and in the RDF-Based Semantics, and without it, an OWL 2
RL rule-reasoner will not match on AllDifferent axioms in older (OWL 1)
ontologies.

Cheers,
Michael
