RFC 4622 XMPP IRIs/URIs July 2006
1. Introduction
The Extensible Messaging and Presence Protocol (XMPP) is a streaming
XML technology that enables any two entities on a network to exchange
well-defined but extensible XML elements (called "XML stanzas") at a
rate close to real time.
As specified in [XMPP-CORE], entity addresses as used in
communications over an XMPP network must not be prepended with a
Uniform Resource Identifier (URI) scheme (as specified in [URI]).
However, applications external to an XMPP network may need to
identify XMPP entities either as URIs or, in a more modern fashion,
