1. Introduction
1.1. Overview
The Extensible Messaging and Presence Protocol (XMPP) [RFC6120] is an
application profile of the Extensible Markup Language [XML] for
streaming XML data in close to real time between any two or more
network-aware entities. The address format for XMPP entities was
originally developed in the Jabber open-source community in 1999,
first described by [XEP-0029] in 2002, and then defined canonically
