Well, not necessarily. It is perfectly legitimate XML to change the default namespace of an element inside an XML document. But, when crossing the C2S -S2S gap in XMPP the server is responsible for not retransmitting stanzas in the jabber:client namespace. If a server simply tacks on the "from" address and forwards the stanza to the S2S socket stream then that is legitimate XML, but bad XMPP. -JD Conley
