Yes, sorry.  I just wanted to make sure everyone was on the same page.

See my other message.  Non-updated copies of the standard and unofficial
code lists were much more common than official subscribed copies of the
standard.  (How many people, even now, know about the special meaning of
"OO" and "OOO" in ISO 3166?  You can really only find out about those by
reading the standard.)

I didn't ask about Date B.  I asked, somewhat rhetorically, because
Addison responded to Kent:

and this came as a surprise to me, based on my understanding of Date B
and File-Date and Added.  So far nobody's responded (it's a nice
weekend).

Kent asked what would happen "when the actual registry goes 'live'."
That could only refer to the initial registry.  I think everyone
understands that the Added dates for existing subtags won't change after
the registry goes live, and indeed draft-registry mandates that.

I wish we did have exact dates for these things.

I didn't ask about Date B.  Really.

We can never tell when there will be "potential major changes" to the
source standards.  With the notable exception of CS, which ISO 3166/MA
apparently knew would cause problems, the MAs don't generally tell us
when there is a change in the works.  They simply announce the change
after it is approved (or in the case of UNSD, post it on the Web with no
announcement).

Section 4 of draft-initial is essentially just a code list, an
"unregistry" as you once called it.  Removing 831 through 833 would not
cause me any grief personally, and we can be fairly sure we will not
have to remove 830.

The editors of draft-registry have essentially mirrored that list in
Section 3.3, point 11, and they can decide whether amending that section
would cause problems.
