Clients are going to need to use a consistent approach to globally unique naming. If they’re not unique then you’ll get collisions and all the benefits are lost. (And if they’re not consistent then they’ll be fingerprintable, which seems like a sensible thing to avoid while we’ve got the chance). /K _______________________________________________ Standards mailing list Info: https://mail.jabber.org/mailman/listinfo/standards Unsubscribe: standards-unsubscr...@xmpp.org _______________________________________________
