Re: Does anyone still think that RECURRENCE-ID's do NOT change?

Would someone please reply to this post so that Doug will
actually see it.  I think we've explained it enough that
he's finally ready to listen to what we've been saying all along.

Here goes:
I define the set of recurring Mondays at SEQ:0
I move one of those Mondays to start on Tuesday at SEQ:1.
That instance, and only that instance are at SEQUENCE 1.

If I was to do a "REFRESH" on the UID I would get back
to VEVENT objects in the same REQUEST.

The first event component says:

SEQ:0
RRULE: Every Monday

The second says:

SEQ:1
RID: Some Monday
DTSTART Some Tuesday


The "set" of every Monday is still intact and has not been changed.
It just so happens that the instance created by "Some Monday" now
starts at "Some Tuesday".

I'll repeat:
The recurrence set still describes every Monday.
The recurrence set is still defined by SEQUENCE:0
The instance of "Some Monday" starts "Some Tuesday" and is
defined by SEQUENCE:1 of RID:"Some Monday".

Again, the repeat set defined by SEQUENCE:0 has not changed.
The only thing that has changed is that one of the instances
calculated by the repeat set actually starts on on a Tuesday.
It is important to note that the RECURRENCE-ID and DTSTART
for that instance DO NOT MATCH.
