[Standards-JIG] proto-JEP: Time Periods

We have to consider that this JEP is giving us the possibility to further
qualify an event with a time period. In its current form, I believe it is up
to the task. And I thank Peter for the quick turn around.
As a more general point, I feel that we must be wary of interpreting
examples given in JEPs or following them to the letter. I would be very much
in favor of adding a note to JEP examples to clearly indicate when they are
only 'informative' or 'normative'. Doing so will probably ease up some of
our discussions ;)
One way to further enhance our process would be to write separate use cases
for different protocol JEPs applications. Similar constructs may be used in
very different cases, and it is a good approach to detail them when a new
application trend is shaping up.
P.S. BTW, another part of the industry has a different view about the
relationship between 'presence' and 'time period' It's probably a matter of

Good beginning, but I dislike all examples :-)
In general, I think that sending along a start time for presence, and
presence sent using pubsub with an ItemID of 'current' makes little sense.
are dealing with a near-realtime communication medium. I can think of two
- Notifications that are delivered some time after the actual publish, but
this would be something that could be changed by resp. the server and
service. Of course, jabber:x:delay comes into mind here as well.
- Automatic away/xa. One could use timeperiod for conveying the beginning
inactivity (which is before sending the presence!).
For pubsub, I think I'd like it better if this extension would be a direct
child of the <item/>.
