The XMPP Standards Foundation (XSF)The XMPP Standards Foundation (XSF) is an independent, non-profit membership organization that develops open extensions to the IETF's Extensible Messaging and Presence Protocol (XMPP). For further information, see <https://xmpp.org/about/xmpp-standards-foundation>. defines protocol suites for the purpose of compliance testing and software certification. This document specifies the 2012 compliance levels for XMPP clients and servers. The XSF neglected to publish compliance suites for 2011; therefore the predecessor to this document is XMPP Compliance Suites 2010 (XEP-0270)XEP-0270: XMPP Compliance Suites 2010 <https://xmpp.org/extensions/xep-0270.html>.. Unless qualified where explicitly noted, support for the listed specifications is REQUIRED for compliance purposes.
* Necessary to support Personal Eventing Protocol (PEP).
** Support can be enabled via an external component or an internal server module/plugin.
*** Support for the Entity Use Cases and Occupant Use Cases is REQUIRED; support for the remaining use cases is RECOMMENDED.
Some of the protocol specifications referenced herein have their own dependencies; developers need to consult the relevant specifications for further information.
Developers are advised to refer to Best Practices for Use of SASL EXTERNAL (XEP-0178)XEP-0178: Best Practices for Use of SASL EXTERNAL <https://xmpp.org/extensions/xep-0178.html>. regarding proper implementation of the SASL EXTERNAL mechanism in XMPP.
This document introduces no additional security considerations above and beyond those defined in the documents on which it depends.
