In my opinion, OWL 2 is a great improvement over OWL 1 since it incorporates several expressive means which are relevant for applications.

However, regarding datatypes the restriction to unary relations (facets) seems unnecessary since concrete domains with n-ary relations are state of the art in DL research, and they certainly are useful in practice, since they allow to express, eg, that a car is at least as heavy as its engine.

It would thus be great if datatype relations with a higher arity could be included in the final version.

Best regards,
