I also agree it is too extreme to restrict to one package per dialog.
But as I stated earlier, I'm fine not defining multiple packages per INFO.

Hi,
I don't have a problem agreeing with that.
Note that buried somewhere in this thread was a question of whether we
had a use case for multiple packages per dialog, or can we simplify even
further.
I don't think we should go that far, because that could become very
restrictive.
For example, assume I want to use INFO packages e.g. for DTMF during the
call setup, and then other INFO package(s) for something else during the
call.

Hi,
I agree with John. Let's keep it simple. If allowing multiple packages
in a single INFO causes issues, let's forget about it.
The whole idea with this is to allow people using INFO to do so in an
easy and standardized way, so let's not shoot ourselves in the foot
with complexity.

Christer

In reply to this whole thread, please bear in mind that we had lots of
discussion about whether it would be worthwhile defining this new INFO
mechanism, since existing applications are unlikely to change and the
best we can hope for is that new applications will exploit the new
mechanism. Therefore we want to keep the mechanism as simple as
possible. The complexities of matching body parts to header fields,
dealing with cases where only some of the packages are understood,
etc.
are hardly likely to persuade people to implement the mechanism.
Please keep it simple.
John

Hi,
Why does putting two different packages in the same INFO
work better
than two different INFO messages each with their own
package usage? Is
there a desirable relationship that can be implemented
between the two
that we would otherwise lose?
We have one package per NOTIFY. Let's stick with one package
per INFO,
unless we want to go back to using mime-types as the only
distinguisher of packages.
I raised that issue in another e-mail.
But, never the less, I have no strong feelings on the single versus
multiple package issue.
Regards,
Christer
