Use PEP (and XEP-0222) for XEP-0292

[singpolyma]

While the existing version says this was rejected by community consensus, since then the consensus of most implementations is to use PEP directly even though it was never specified to work, and that the raw-IQ protocol adds complexity. This update removes the raw-IQ mode and specifies the reuse of PEP.

Why change this? Asked in xsf@

[singpolyma]

I thought it was more clear for the ID here to match the ID in the publication example above, as this is an example notification about that publication, in effect.

[horazont]

But shouldn't the publication also use id='current' to avoid to accumulate ever more items?

[singpolyma]

Probably pubsub#max_items should be set to 1 for the node.

[Zash]

(tho you'd probably limit the node to 1 item)

[stpeter]

Did this conversation get resolved?

[Zash]

Dunno, should it follow the singleton pattern or nah?

[singpolyma]

Given what the XEP already says

Note: There is no payload, because this is a pure notification (the receiver needs to retrieve the vCard using an IQ-get as described earlier).

I think as it was written (using current) is basically not usable because you will always get a notification on connect that says "vcard is current" which... is just obviously true and tells you no information?

@stpeter You're probably the easier of the two Authors to get hold of to approve this :)

This also needs a version block.
