The Extensible Messaging and Presence Protocol (XMPP) is defined in the XMPP Core (RFC 3920) and XMPP IM (RFC 3921) specifications contributed by the XMPP Standards Foundation to the Internet Standards Process, which is managed by the Internet Engineering Task Force in accordance with RFC 2026. Any protocol defined in this document has been developed outside the Internet Standards Process and is to be understood as an extension to XMPP rather than as an evolution, development, or modification of XMPP itself.
The following keywords as used in this document are to be interpreted as described in RFC 2119: "MUST", "SHALL", "REQUIRED"; "MUST NOT", "SHALL NOT"; "SHOULD", "RECOMMENDED"; "SHOULD NOT", "NOT RECOMMENDED"; "MAY", "OPTIONAL".

Revision History
The XMPP Standards Foundation (XSF) [1] 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:
Table 1: Required and Recommended Specifications
| Specification | Requirement Level |
|---|---|
| rfc3920bis [2] | REQUIRED * |
| rfc3921bis [3] | REQUIRED * |
| Service Discovery [4] | REQUIRED |
| JID Escaping [5] | RECOMMENDED |
| Entity Capabilities [6] | REQUIRED |
| Stream Compression [7] | RECOMMENDED |
* Note: XMPP Core [8] and XMPP IM [9] are currently being revised to incorporate errata and feedback based on implementation experience; because it is expected that the revision process will be complete well before this compliance level takes effect, developers are advised to implement the specifications as defined in draft-saintandre-rfc3920bis and draft-saintandre-rfc3921bis rather than RFC 3920 and RFC 3921.
Some of the protocol specifications referenced herein have their own dependencies; developers must refer to the relevant specifications for further information.
This document introduces no additional security considerations above and beyond those defined in the documents on which it depends.
This document requires no interaction with the Internet Assigned Numbers Authority (IANA) [10].
This document requires no interaction with the XMPP Registrar [11].
