Do you know this draft? <http://tools.ietf.org/wg/simple/draft-garcia-simple-presence-dictionary-05. txt> http://tools.ietf.org/wg/simple/draft-garcia-simple-presence-dictionary-05.t xt I think it addresses the same problem you are trying to solve, but using the standard SigComp framework (RFC3320).

From: ajay.kasam@wipro.com [mailto:ajay.kasam@wipro.com] Sent: jueves, 28 de junio de 2007 13:21 To: simple@ietf.org Subject: [Simple] Binary XML format for Presence Information Hi All, Problem: The Presence information for the presentity is too large if represented in XML textual format. For the low bandwidth networks, it would be better if we reduce the network bandwidth requirements for presence information state change exchange. Current solutions: The current solution is uploading presence information to HTTP content server and its HTTP URI is sent to the watcher for the state information. In this case, user got to use another protocol to download the content. Though different mechanism, the network bandwidth requirement is same. This mechanism doesn't solve the actual problem of reducing the bandwidth requirement. Proposed Solution: Coming up with binary format for representing the presence information. Associating each of PIDF XML tag with a binary code and using this mechanism to convey the presence information(state change). This is inspired from "DRM Rights in binary format application/vnd.oma.drm.rights+wbxml (http://www.openmobilealliance.org/release_program/docs/DRM/V1_0-20040625-A/ OMA-Download-DRMREL-V1_0-20040615-A.pdf)".
