Asking again isn't going to turn one up.
The participants on this thread have been presenting the various
rationales that led to the non-acceptance of the "recent proposal"
that Bob Hallissy is referring to. That is basically the best
you are going to get.
I think you may have some fundamental misapprehensions about how
standards committees in general operate, as well as the UTC and
WG2 in particular.
The presentation of a proposal to a standards committee isn't like
an application for a license from a government agency (or something
similar), for which the applicant has some kind of legal entitlement
and rights to appeal and rights to explicit provision of reasons
if the application is turned down.
A proposal in a standards committee initiates a process of
consideration and discussion, which may or may not result in a
formal ballotting involving some aspect of the proposal. Failure
to reach agreement on a proposal (either unanimous or by a voting
consensus process of some sort) does not obligate the committee
to then provide a formal rationale why agreement could not be
reached. It is simply a failure to reach agreement to do whatever
may have been proposed.
In the ISO process, once a particular standard or change to a
standard is in formal ballotting, national bodies may provide
technical or editorial comments accompanying their ballots. The
editor of the relevant standard provides formal written disposition
of comments, and those dispositions generally do provide rationales
for decisions taken on those comments -- as agreed by the relevant
working group. You can find many such examples in the ISO JTC1/SC2/WG2
document archives regarding the development of ISO 10646. But
as Bob and Peter pointed out, this particular proposal has
never reached a stage of formal ballotting in ISO.
The Unicode Technical Committee also does post a little information
about the simple cases where a proposal to encode one or more
characters did not find agreement in the committee:
But the rationale for that page is mostly to keep people from
independently coming back to again request encoding of something
that was rejected (and would likely be rejected again), and for
which a simple or obvious reason was available.
There are many other instances, however, of proposals to the UTC
which failed to attain agreement for one reason or another, which
are *not* documented on that page, often because provision of a
rationale to explain the situation would be too extensive to fit
meaningfully into a simple HTML table cell entry. In extreme
cases, there may not be *a* rationale at all -- simply many
different objections of different grounds, leading to the inability
to take any decision.
The situation for diacritical extension of basic Arabic letters
is a complex one involving decades of existing encoding practice
at this point, long preceding the development of Unicode. It also
involves complex issues of stabilization of of data under
normalization, as well as model issues for the implementation of
rendering. People on this list can discuss those issues further
and explain why it is unlikely that the UTC would reconsider
and take up a dynamic model for the encoding of Arabic letter
diacritics, but that is probably all they can do at this point.
If what you are looking for is a flawed, written rationale for
a rejection which you can then appeal to a higher committee for
reversal of decision -- well, you aren't going to find that,
because that's not how this process works.
Your task, instead, would be to create a consensus within the
character encoding community (and the implementing information
technology companies) that the existing Arabic encoding is so
flawed that it requires introduction and implementation of
a competing, distinct textual representation in Unicode.
That, sir, is a *very* high mountain to climb, at this point.
