I would be careful about trying to take the network locator/identifier
discussion into UR* space. A locator in the network gives you a network
attachment point, not the object attached to it. Also there are many
identifiers that are unrelated to any locators. The mapping to app space
isn't very good and using locator/identifier could produce confusing
results.

Perhaps you could think of URLs as naming "instances"?
