+/**
+ * Represents a stream error packet. Stream errors are unrecoverable errors where the server
+ * will close the unrelying TCP connection after the stream error was sent to the client.
+ * These is the list of stream errors as defined in the XMPP spec:<p>
+ *
+ * <table border=1>
+ * <tr><td><b>Code</b></td><td><b>Description</b></td></tr>
+ * <tr><td> bad-format </td><td> the entity has sent XML that cannot be processed </td></tr>
+ * <tr><td> unsupported-encoding </td><td> the entity has sent a namespace prefix that is
+ * unsupported </td></tr>
+ * <tr><td> bad-namespace-prefix </td><td> Remote Server Timeout </td></tr>
+ * <tr><td> conflict </td><td> the server is closing the active stream for this entity
+ * because a new stream has been initiated that conflicts with the existing
+ * stream. </td></tr>
+ * <tr><td> connection-timeout </td><td> the entity has not generated any traffic over
+ * the stream for some period of time. </td></tr>
+ * <tr><td> host-gone </td><td> 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. </td></tr>
+ * <tr><td> host-unknown </td><td> 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. </td></tr>
+ * <tr><td> improper-addressing </td><td> a stanza sent between two servers lacks a 'to'
+ * or 'from' attribute </td></tr>
+ * <tr><td> internal-server-error </td><td> the server has experienced a
+ * misconfiguration. </td></tr>
+ * <tr><td> invalid-from </td><td> the JID or hostname provided in a 'from' address does
+ * not match an authorized JID. </td></tr>
+ * <tr><td> invalid-id </td><td> the stream ID or dialback ID is invalid or does not match
+ * an ID previously provided. </td></tr>
+ * <tr><td> invalid-namespace </td><td> the streams namespace name is invalid. </td></tr>
+ * <tr><td> invalid-xml </td><td> the entity has sent invalid XML over the stream. </td></tr>
+ * <tr><td> not-authorized </td><td> the entity has attempted to send data before the
+ * stream has been authenticated </td></tr>
+ * <tr><td> policy-violation </td><td> the entity has violated some local service
+ * policy. </td></tr>
+ * <tr><td> remote-connection-failed </td><td> Rthe server is unable to properly connect
+ * to a remote entity. </td></tr>
+ * <tr><td> resource-constraint </td><td> Rthe server lacks the system resources necessary
+ * to service the stream. </td></tr>
+ * <tr><td> restricted-xml </td><td> the entity has attempted to send restricted XML
+ * features. </td></tr>
+ * <tr><td> see-other-host </td><td> the server will not provide service to the initiating
+ * entity but is redirecting traffic to another host. </td></tr>
+ * <tr><td> system-shutdown </td><td> the server is being shut down and all active streams
+ * are being closed. </td></tr>
+ * <tr><td> undefined-condition </td><td> the error condition is not one of those defined
+ * by the other conditions in this list. </td></tr>
+ * <tr><td> unsupported-encoding </td><td> the initiating entity has encoded the stream in
+ * an encoding that is not supported. </td></tr>
+ * <tr><td> unsupported-stanza-type </td><td> the initiating entity has sent a first-level
+ * child of the stream that is not supported. </td></tr>
+ * <tr><td> unsupported-version </td><td> the value of the 'version' attribute provided by
+ * the initiating entity in the stream header specifies a version of XMPP that is not
+ * supported. </td></tr>
+ * <tr><td> xml-not-well-formed </td><td> the initiating entity has sent XML that is
+ * not well-formed. </td></tr>
