mod_pubsub: Normalize 'publisher' JID All the XEP-0060 examples have the publisher attribute set to a bare JID, but the text does allow it to be the full JID. Since mod_pubsub is more likely used for open nodes that anyone can subscribe to it makes sense to not leak the full JIDs. This is also disabled by defaults. In mod_pep on the other hand it might make sense to have the full JID since that data is more likely to be broadcast to contacts which are already somewhat trusted.
