Hello, The problems with anonymous individuals that I noticed in the Profiles made me look again at the global restrictions on anonymous individuals in Section 11.2. I noticed a slight error in the global restrictions, which I've fixed. After fixing this error, I realized that - the restriction on no anonymous individuals in OWL 2 EL and OWL 2 QL is strictly needed if we don't want to lose good computational properties; - however, in OWL 2 RL this restriction isn't needed -- that is, even with anonymous individuals reasoning in OWL 2 RL can be implemented in polynomial time. Consequently, I've removed the restriction on no anonymous individuals in OWL 2 RL from the Profiles document. I'm now done with all my changes to the spec -- we are ready to roll! Regards, Boris
