|
|
The &XSF; defines protocol suites for the purpose of compliance testing
|
|
and software certification.
|
|
This document specifies the 2017 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.
|
|
A feature is considered supported if all comma separated feature providers
|
|
listed in the "Providers" column are implemented (unless otherwise noted).
