Hi, As this draft mentioned, the presence rules may affect the views of the resource state. If the presence rules of presentity are modified, all of etags for this presentity have to be abandoned. Or the PS has to evaluate whether each etag still is valid.
For filtering, there is similar problem: http://www1.ietf.org/mail-archive/web/sip/current/msg19724.html These are difference between HTTP and SIP events framework.
