IPP>MOD Concern about Event Notification Content

Carl-Uno,


You're correct in that it probably won't take much time to hack
up the existing text to nail down some kind of encoding that would
be palatable to the IESG or whomever.


That is not what concerns me about IPP notification, however.
What does concern me is that no one has offered up any REAL
scenarios illustrating how IPP notification would actually work.


Sure, people have made comments to the effect of "just send an email
message".  But I think we really need to walk thru multiple (not
just one) method of using IPP notification data to ensure that the
resulting facility is indeed useful as designed.


Do I have any suggestions?  Not at this time...which is one reason
I suggested we defer this entire capability until the next version
of IPP.


Event notification is NOT something we want to take lightly, nor
do a half-baked job.  Believe me, after spending the last 2 years
on SENSE development, it's pretty easy to hack together a "solution"
that appears to be useful, but ultimately falls short in the long
run.  (That's not to say our SENSE implementation falls short,
mind you...  ;-)
