    <p>
      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.
