The main points re pdam-1 that we must be hard on are

- The base mechanism for transform from some reasonable number (like 1 M) of
UCS-4 code points to the form where they can be accessed by UCS-2 systems.

- reservation of the S zone for this mechanism. This implies that we can start
allocating the queue of requested characters to either the BMP outside the S
zone and/or the appropriate area of UCS-4

The other stuff is pretty much all secondary - i.e. we do not let it get in
the
way of the two main points. Thus this was originally positioned as a UCS-2E
'form of use' - changed to a transformation format as a tactic, now some are
arguing for the first format. I do not believe that it much matters which wins
out. We should back whatever is pragmatic and should certainly not be raising
these 'problems' ourselves.

I would like some guideance (from Mike perhaps) on the impact of the annex
being
normative or non normative. It seems that it is not necessary to have annex O
normative to reserve the S zone, since this is done as a change to the main
body
(section 8) - does the annnex need to be normative to enable a reference to it
from the main standard?

Any system that is today conformant to 10646 should not become non conformant
if
the two PDAM's are approved. I presume that this is the case?
