<section1 topic='Introduction' anchor='intro'>
|
|
<p>
|
|
The &XSF; defines protocol suites for the purpose of compliance testing
|
|
and software certification.
|
|
This document specifies compliance levels for XMPP clients and servers; it
|
|
is hoped that this document will advance the state of the art, and provide
|
|
guidance and eventual certification to XMPP client and server authors.
|
|
</p>
|
|
<p>
|
|
This document defines <strong>Categories</strong> based on
|
|
typical use cases (Core, Web, IM, Mobile) and <strong>Levels</strong>
|
|
(Core, Advanced) based on functionality in the respective category.
|
|
</p>
|
|
<p>
|
|
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).
