<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.
There is a growing number of XMPP Extension Protocols (XEPs) that provide
different building blocks for XMPP-based applications. XMPP software
developers are confronted with the challenge of finding the right
combination of XEPs for a given application profile. Users need a way to
compare applications without resorting to comparing for individual XEP
numbers.

This document defines XMPP application <strong>Categories</strong> based on

(Core, Advanced) based on functionality in the respective category. For
each combination of those, the required XEPs are referenced. As the
protocol landscape changes over time, this document is updated roughly
once a year.
</p>
<p>
For developers, this document provides guidance on which specifications
they need to consider when implementing an application of a certain kind.
By completing a compliance test or performing a self-assessment, they can
advertise their implementation as compliant with a given Category and
Level.
</p>
<p>
For users, this provides an easy way to compare implementations based on
their respective advertised compliance levels and year.
