Oops, yes. Apologies for that error.

I have seen people trying to declare range and domain semantics for
"all instances of a certain subClassOf rdf:Property" though. In fact,
DAML does something like that, as I recall.

Ah, the *set* of subClasses, not a particular set. Well, thanks to
DanC coming up with a neat little vocabulary for that and given it a
date-stamped W3C URI, I guess the case is closed :-)
