Subject: [Simple] New version of XCAP usage for manipulating presence document contents

Hi,

I have submitted a new version on the XCAP application usage for manipulating the content of PIDF presence document, previously known as XCAP usage for presence publishing. 

You can find it at:
http://www.ietf.org/internet-drafts/draft-isomaki-simple-xcap-pidf-manipulation-usage-00.txt
(Note that actually this has been approved as SIMPLE WG item, but due to my typo, it is still named as an individual draft.)

The main idea of the draft is to complement SIP PUBLISH to allow the presentity to manipulate device independent "hard state" presence information. This hard state information would be fed to the presence composition process as one input alongside the PUA views published using SIP.

There are no open issues as such within the draft, the updates compared to the last version were mainly about better wording. However, there is one big issue wrt. the latest discussion on SIP PUBLISH. There has been a proposal (on SIP WG list) to enhance PUBLISH solution so that PUAs would be able to learn the states set by each other and actually override such states. If this is brought forward PUBLISH will really start overlapping with the XCAP usage defined here. I will continue this discussion on SIP WG mailing list.

Regards,
	Markus
