A JID is made up of a node (generally a username), a domain, and a resource. The node and resource are optional; domain is required. In simple ABNF form: <ul><tt>jid = [ node "@" ] domain [ "/" resource ]</tt></ul> Some sample JID's: <ul> <li><tt>user@example.com</tt></li> <li><tt>user@example.com/home</tt></li> <li><tt>example.com</tt></li> </ul> Each allowable portion of a JID (node, domain, and resource) must not be more than 1023 bytes in length, resulting in a maximum total size (including the '@' and '/' separators) of 3071 bytes.<P><P><DL><DT><B>Author:</B></DT> <DD>Matt Tucker</DD><DT><B>See Also:</B><DD><A HREF="../../../serialized-form.html#org.xmpp.packet.JID">Serialized
