Subject: [Simple] delivering Presence Authorization Rules to Presence Service with SIP

Hi

Has there been any discussion or initiations on sending Presence Authorization Rules (as defined in draft-ietf-simple-presence-rules-02) via SIP by using e.g. PUBLISH method or something?
Now it is possible to subscribe presence and watcher info and to deliver presence information with SIP. It might be handy to be able to send also Presence Authorization Rules using SIP and have working Presence Service using SIP for all communications and not to use XCAP (HTTP) at all.. Sounds simpler to me at least..
Of course XCAP has advantage on partial manipulation of complex data but in simple scenarios it just adds unnecessary complexity (on both terminal and presence server implementation) compared to all SIP alternative. Or have I missed something?

Regards,
Henrikki
