John,
as you can read on the "Correlate sip sessions/dialogs" mail thread we
are trying to merge in one draft
all the different requirements currently spread in three drafts.
In that draft we will have two separate set of requirements one for
"media session correlation" and another
for "dialog correlation".
So it could be hard not to refer to dialogs at all.
However as I said we will do our best to make the requirement as general
as possible

Sal,
It should be possible to express requirements without referring to
dialogs. Any reference to dialogs seems to make some assumption about
solution.

Req A: It must be possible, when establishing a dialog,
to specify
that
it be correlated with one or more already existing dialogs, which
dialogs, at the time they were created, did not need to
specify that
they might be correlated with in the future.
[JRE] I don't think this is a valid requirement, because it has a
particular class of solutions in mind. In my opinion the basic
requirement should be something along the lines of "It
must be possible
to establish, modify and clear down a multimedia session
between two
parties, one or both of which use different devices for different
media."
John
I agree with John.
Paul
I agree on the fact that the requirements have to be as
general as possible.
In fact if you read my mail "Correlate sip sessions/dialogs"
you can see
we have already have two requirements that are similar
(almost equal) to
the one suggested by John.
The requirement in this mail was about the possibility to create the
initial dialog without knowing
in advance whether another dialog will want to correlate with it.
We can generalize it:
"It must be possible to create a dialog without knowing in advance
whether or not
another dialog will want to correlate with it"
Maybe it is a redundant requirement but at this stage there are
people that think it should be specified.
Sal
