Note: This protocol suite is obsolete. For updated protocol suites, refer to XMPP Intermediate IM Client 2008 (XEP-0213) [1] and XMPP Intermediate IM Server 2008 (XEP-0216) [2].
The Basic IM Protocol Suite (XEP-0073) [3] introduced the concept of a "protocol suite". This document extends the basic support specified in Basic IM Protocol Suite (XEP-0073) [3] by specifying an Intermediate IM Protocol Suite.
This document follows the same approach as Basic IM Protocol Suite (XEP-0073) [3]. By design, the Basic IM Protocol Suite does not include more advanced instant messaging functionality; the present document fills the need for a protocol suite that addresses such functionality.
A protocol is deemed worthy of inclusion in this protocol suite if:
We define the Intermediate IM Protocol Suite as follows:
| Specification | Requirement Level |
|---|---|
| XEP-0073: Basic IM Protocol Suite | REQUIRED |
| Multi-User Chat (XEP-0045) [5] | REQUIRED |
| XHTML-IM (XEP-0071) [6] | REQUIRED |
| SI File Transfer (XEP-0096) [7] | REQUIRED |
| Entity Capabilities (XEP-0115) [8] | REQUIRED |
Note well that the foregoing protocols apply to clients only (i.e., they do not introduce new requirements for servers). In addition, these protocols have their own dependencies, which include the following XEPs (as well as various IETF RFCs and W3C specifications):
In addition, because the intermediate suite builds on the basic suite, by definition all protocols required by Basic IM Protocol Suite (XEP-0073) [3] are also required by the intermediate suite (refer to XEP-0073 for details).
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) [16].
No namespaces or parameters need to be registered with the XMPP Registrar [17] as a result of this document.

Per a vote of the XMPP Council, changed status to Obsolete and referred implementors to XEP-0213 and XEP-0216.
