You're assuming there's a workable notion of extrinsic identity, which has never been achieved (for all that the notion appears to be simple and desirable). There are too many nuances to "identity". Tossing another monkey wrench in the soup ... what about agents on the network who are trying to deceive you to make you act in some particular way? The web clearly has such agents. What's the consequence of asking such a question of such an agent, and acting on its incorrect answer? (Or acting on such an incorrect answer even in the face of an honest human mistake, or some sort of system fault?) - Dave xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
