[Standards] DRAFT: XEP-0319 (Last User Interaction in Presence)

Hi Tobias,

@XML Schema: I think the "since" attribute should be xs:dateTime, like in:
and probably most other XEP which deals with date/time.

On the other hand I saw that XEP-0202 uses xs:string, too. (probably a mistake)

Otherwise looks good.
What about my point 1 (The correlation to XEP-0012 4. Online User Query)?

And a last note: Some protocols (XEP-0202, XEP-0203) explicitly state, that the date/time used must be expressed in UTC. I don't know if you want that to be a requirement for XEP-0319, too. (I see no requirement for it, but I also don't see one for XEP-0203).

Does superseding happen at Draft or Final?
This does not seem to be defined in XEP-0001. At least I did not find anything specific about when it is supposed to happen.

I've just added the XML Schema. Feel free to review: https://gitorious.org/xmpp/xmpp/commit/ad8bc9066902a6e56112b60eb8bb5f5b9b4b3572[https://gitorious.org/xmpp/xmpp/commit/ad8bc9066902a6e56112b60eb8bb5f5b9b4b3572]
> 4. „Determing Support“ is missing. I am not sure, if it’s necessary at all (because there’s no real interaction), but most other XEP’s have this.

I don't think this protocol needs this.  Entities that receive the
extension and don't understand it MUST ignore it.
Completely agree here. I can not think of an UX or protocol issue that would be solved by knowing the other party supports this XEP or not before actually receiving an idle-annotated stanza.
