Why is UniqueProperty a subclass of rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Property whereas UnambiguousProperty is a subclass of #ObjectProperty? This seems especially odd in view of this statement (from the language reference doc): Note that the inverse property of a UniqueProperty is always an UnambigousProperty and vice versa. I sort of thought a design decision had been made that each DAML property should be either Object or Datatype, and that this distinction was supposed to be made clear in its declaration (someone please correct me if I'm wrong). But, if that's right, UniqueProperty allows one to get around that design decision. - David
