iTIP: Outdated VTIMEZONE

Hi folks,

I had a question while reading ITIP.

Suppose a CUA receive a VCALENDAR object, containing a VTIMEZONE
with outdated datas (as far as the concerned CUA thinks).

An example related is shown below.

What is the correct behavior is this case?

I believe the CUA should send a COUNTER proposal with the
corrected VTIMEZONE component (then following the described
workflow for COUNTER proposals).

If I am right, may this process be described in iTIP?

Antoine
