This works for me except for anycast. The problem is that if you have an anycast address you might not _need_ to change it if you move to a different point of attachment, and since that particular point of attachment might not have any other name associated with it, IMHO within a single network, anycast _does_ name a particular point of attachment. So I'm back to the suggestion I made before you included "at a given layer": a locator is a name for a point of attachment, and if an object moves its associated locator(s) might not change but it cannot assume that they will not. Perhaps the text could say "may have to change" or "cannot be expected not to change". > identifier An identifier is the name of an object at a given layer; > identifiers have no topological sensitivity, and do not > have to change, even if the object changes its point(s) of > attachment within the network topology.
