  the entity has sent a namespace prefix that is
 *          unsupported 
 bad-namespace-prefix 
 Remote Server Timeout 
 conflict 
 the server is closing the active stream for this entity
 *          because a new stream has been initiated that conflicts with the existing
 *          stream. 
 connection-timeout 
 the entity has not generated any traffic over
 *          the stream for some period of time. 
 host-gone 
 the value of the 'to' attribute provided by the initiating
 *          entity in the stream header corresponds to a hostname that is no longer hosted by
 *          the server. 
 host-unknown 
 the value of the 'to' attribute provided by the
 *          initiating entity in the stream header does not correspond to a hostname that is
 *          hosted by the server. 
 improper-addressing 
 a stanza sent between two servers lacks a 'to'
 *          or 'from' attribute 
 internal-server-error 
 the server has experienced a
 *          misconfiguration. 
 invalid-from 
 the JID or hostname provided in a 'from' address does
 *          not match an authorized JID. 
 invalid-id 
 the stream ID or dialback ID is invalid or does not match
 *          an ID previously provided. 
 invalid-namespace 
 the streams namespace name is invalid. 
 invalid-xml 
 the entity has sent invalid XML over the stream. 
 not-authorized 
 the entity has attempted to send data before the
 *          stream has been authenticated 
 policy-violation 
 the entity has violated some local service
 *          policy. 
 remote-connection-failed 
 Rthe server is unable to properly connect
 *          to a remote entity. 
 resource-constraint 
 Rthe server lacks the system resources necessary
 *          to service the stream. 
 restricted-xml 
 the entity has attempted to send restricted XML
 *          features. 
 see-other-host 
  the server will not provide service to the initiating
 *          entity but is redirecting traffic to another host. 
 system-shutdown 
 the server is being shut down and all active streams
 *          are being closed. 
 undefined-condition 
 the error condition is not one of those defined
 *          by the other conditions in this list. 
 unsupported-encoding 
 the initiating entity has encoded the stream in
 *          an encoding that is not supported. 
 unsupported-stanza-type 
 the initiating entity has sent a first-level
 *          child of the stream that is not supported. 
 unsupported-version 
 the value of the 'version' attribute provided by
 *          the initiating entity in the stream header specifies a version of XMPP that is not
 *          supported.

 *          not well-formed.
