Changed XMPP Core and XMPP IM references to bis drafts; added implementation notes.

 0.2 2007-05-11 psa

Added JID Escaping (XEP-0106) and Stream Compression (XEP-0138) as recommended.

Initial published version.

First draft, split from XEP-0073.

The &XSF; defines protocol suites for the purpose of compliance testing and software certification. This document specifies the XMPP Basic Client 2008 certification level.

The XMPP Basic Client 2008 certification level is defined as follows:

Specification Requirement Level
&rfc3920; REQUIRED *
&rfc3921; REQUIRED *
&xep0030; REQUIRED
&xep0106; RECOMMENDED
&xep0115; REQUIRED
&xep0138; RECOMMENDED

* Note: RFC 3920 and RFC 3921 are currently being revised to correct errors, clarify matters that were underspecified, and incorproate feedback based on implementation and deployment experience gained since RFC 3920 and RFC 3921 were published in 2004. Although the compliance level specified herein refers to RFC 3920 and RFC 3921, developers are also advised to consult &rfc3920bis; and &rfc3921bis;, which provide the most up-to-date and accurate description the core XMPP protocols.

Some of the protocol specifications referenced herein have their own dependencies; developers must refer to the relevant specifications for further information.

Developers are advised to refer to &xep0178; regarding proper implementation of the SASL EXTERNAL mechanism in XMPP. Given the wide deployment of domain certificates issued by the XMPP Intermediate Certification authority, developers should also consider bundling the root certificate of the &SFSCA; with their software. The root certificate is located at "http://cert.startcom.org/ca.crt", to be superseded in future years by the root certificate located at "http://cert.startcom.org/sfsca.crt". It is not necessary for clients to bundle the ICA certificate since the full certificate chain should be presented by deployed servers.

This document introduces no additional security considerations above and beyond those defined in the documents on which it depends.
