Well I for one studied the tradeoff carefully (see graph below) and came to
the conclusion that I could write a engine that would make the correct
entailments for all the cases unless the WG made some really off the wall
decision.   I also came to the conclusion that I would want the answers to
Tests A and Tests D both to be 'yes'.  Since that option was not given to
me, I ruled my comments (related to there being two different copula in
question here: equality and identity, but only one mentioned in the
questions) off topic.   But it sure did not feel right being presented with
two options neither of which was acceptable ... especially since I've been
waiting for some resolution to this long debate so that I might implement
conforming rdf datatypes in my agent.

I agree with Peter, the question was ill formed.  I do object to walking
over a body dressed in a shirt that is totally black or totally white ;-(
