Let's say that we received the URN from a reasonably but not completely reliable spy; it could be for industrial espionage, military spying, or private detective work; it doesn't matter. Knowledge of whether the URN is valid helps to confirm the reliability of the data, whether or not we can actually resolve the URN. If we cannot verify whether it is even a valid URN (much less resolve it), the knowledge that there might be such a URN is pretty much useless. ====================================================================== Mark Fisher Thomson Consumer Electronics fisherm@indy.tce.com Indianapolis, IN
