Yes, though this isn't as useful as one might think :)

It also provides for annotations on *axioms*.

One should note that OWL Full already provides entity annotations  
(OWL 1.1 provides a "DL friendly, very weak version of that).

You could use punning to do this.

Punning should work for that; it was a primary use case at least I  
had in mind.

Whether it's the *best* way to do this overall, or whether enhancing  
annotation properties would be better is a subtle question :)

Hope this helps.

You can experiment with this in the 1.4 (almost) release of Pellet.
