XML
XML, Extensible Markup Language, is a universal format for structured documents
and data on the Web. The entire Jabber protocol is based on XML and XML
Namespaces. The XML standard is being developed and maintained by the W3C (see
http://www.w3.org/XML/).
XML namespace
An XML namespace provides a simple method for qualifying element and attribute
names used in XML documents by associating them with namespaces identified by a
URI reference. The XML Namespace specification is currently a recommendation
with the W3C (see http://www.w3.org/TR/1999/REC-xml-names-19990114/).
XMPP
XMPP, eXtensible Messaging and Presence Protocol, is the part of the Jabber XML
Protocol that supports Instant Messaging functionality.
XMPP director
The XMPP director handles communication between the core router and Jabber IM
clients. It is configured within a JSM command processor in a Connection Manager.
XMPP Extensions (XEPs)
The Jabber Software Foundation (JSF) develops extensions to XMPP through a
standards process centered around XMPP Extension Protocols (XEPs). The process is
managed by the XMPP Extensions Editor and involves intensive discussion on the
Standards-JIG mailing list, formal review and voting by the XMPP Council, and
modification based on implementation experience and interoperability testing. See
(http://www.xmpp.org/extensions/) for a list of all XEPs (formerly known as JEPs).
XMPP incoming server director
The XMPP incoming server director handles packets being sent to the router from
remote servers. It is configured within an S2S command processor.
XMPP outgoing server director
The XMPP outgoing server director handles packets being sent from the router to
remote servers. It is configured within an S2S command processor.
