I agree.  The framework proposed in draft-kaplan-sip-info-events-01 seems
like a step in the right direction.

And I agree with registering existing uses.   Even if existing uses aren't
updated to use the negotiation mechanism suggested (or whatever solution
the WG converges on), I think there is value in strongly encouraging the
adoption of the 'Info-Package' header (or similar).  This shouldn't
noticeably affect interop of legacy devices, but marking the requests like
this would allow more recent devices to act appropriately in the presence
of multiple incompatible non-standard extensions.  Not that such things
exist, of course!

Michael
