Good point. How much do the X.501 and DID use cases overlap? I always wondered why X.501 wasn't used for more things.

Because all the X.500 standards are terrible designed by commitee things that try to be everything but end up doing nothing specific well.

DID is pretty much the same thing re-packaged in modern buzzwords and encoding.
