|
The &XSF; defines protocol suites for the purpose of compliance testing
|
|
and software certification. This document specifies the 2016 compliance
|
|
levels for XMPP clients and servers; it is hoped that this document will
|
|
advance the state of the art, and provide guidence and eventual
|
|
certification to XMPP client and server authors. Unless explicitly noted,
|
|
support for the listed specifications is REQUIRED for compliance purposes.
