SENT: <iq type="get" id="JCOM_10"><query 
xmlns="jabber:iq:auth"><username>y2k</username></query></iq>

RECV: <iq type='result' id='JCOM_10'><query 
xmlns='jabber:iq:auth'><username>y2k</username><password/><digest/><sequence>460</sequence><token>3B256557</token><resource/></query></iq>

SENT: <iq type="set" id="JCOM_11"><query
