RE: Gen-ART LC review of draft-faltstrom-5892bis-04

Hi Paul,
My understanding that the new value does not replace the current one since
5892bis is not updating rfc5892. So should the IANA registry reflect that
you are not replacing the current value or is my understanding wrong

I saw that in the beginning it has as reference RFC 5892 for the
whole
table. Will it stay this way after the change proposed in this draft
and
just the three individual values will change based on 1.1, 1.2 and
1.3? or
are there no changes in the IANA registry at all. This is unclear to
me
according to the section 3 of your draft.

The table will likely change, based on the input of the expert
reviewer. I assume that a reference to this RFC-to-be would be added to
the top of the table, next to "[RFC5892]". That is, this would be an
additional reference, not a replacement. But that's up to IANA.

Section 5.1 of RFC5892 says "If non-backward-compatible changes or
other
problems arise during the
  creation or designated expert review of the table of derived
property
  values, they should be flagged for the IESG." . My question was if
the
change is backward compatible. The 5892bis draft does not say it.

The draft says:
   This imply the derived property value differs
   depending on whether the property definitions used are from Unicode
   5.2 or 6.0.
We intended that as "non-backwards-compatible"; we can change the
wording to make that explicit.
