Why is XEP-0386 (BIND2) talking about <authorization-identity/> at [1] whereas XEP-0388 (SASL2) is talking about <authorization-identifier/> at [2]? Bot specs use it for exactly the same thing: communicating the bare or full jid (if a bind occured). Why this double-element? XEP-0388 even states which contains an <authorization-identifier/> element containing the negotiated identity - this is a bare JID, unless resource binding has occurred, in which case it is a full JID. So it seems like a perfect fit to communicate the full jid after bind using the SASL2 element, why was this extra BIND2 element added? -tmolitor [1] https://xmpp.org/extensions/xep-0386.html#identifiers [2] https://xmpp.org/extensions/xep-0388.html#success
