AFAIK, there is no Language committee.  The Ada Rapporteur Group (ARG)
is probably an institution which comes close (at least in function).
It handles defect reports for the ISO Ada standard and examines future
directions of the language (for the next revision of the standard, see
http://www.*-*-*.com/ ).

The compiler developers participate, of course.  After all, they're
quite familiar with the language, so their input is appreciated.

Wearing my Ada hat, I do not understand this question.  However, if I
put it off and try my C hat, I can understand what you mean. :-/

Ada vendors usually don't derivate from the language standard in any
significant way, that's why we have the standard. ;-)

Some vendors provide additional features, of course, some of them
are even comparable and compatible, but these extensions don't
play a major role, unlike the 'extensions' over the standard many
C implementations provide (mainly adherence to mostly unwritten
conventions).

In contrast to many other popular programming languages, there is a
publicly available test suite for Ada implementations, and compiler
vendors seek independent validation of their products against this
test suite because it's quite difficult to sell a compiler which
hasn't been validated on at least some platforms.  There's no market
for proprietary Ada dialects at the moment, which is probably a good
thing.

IMHO, a group like the ARG is necessary if you have such a complex
technical specification like a programming language standard.  This is
not a question of regulation, it's a technical necessity.

This does not appear on my newsreader to be posted to any other groups
besides Comp.Lang.Ada. Were you figuring on independently checking all of
the language groups for followups? Or is it a problem with my newsreader?

Since Ada is one of the few OO languages out there with an ISO standard and
test suite and a history of standard-adherence among compiler vendors, it
would be interesting to see how other languages stack up against it. Other
languages have standards, to be sure, but divergence from the standards
seems to be more the rule than the exception. In this respect, Ada has done
famously well - if one considers standard-adherence to be a good thing.

Actually there are language test suites for other popular languages and
a testing center available for performing formal certifications
(http://eds-conform.com/ValProdList.html).  EDS provides conformance
testing for Ada, C, C++, COBOL, Fortran, and SQL.

As Phil Brashear has periodically lamented, no one outside the Ada
community has undertaken a language conformance assessment.

ISO has a working group (working group 9, "WG9") devoted
to the Ada language.  This is the "language committee"
in the official sense.  The ARG is a subgroup of WG9.
There are other "rapporteur" groups within WG9, for example
the ASIS-RG, which work on standards related to Ada.

The ARG focuses on the language standard itself.
The ARG makes recommendations to WG9.  WG9 is the
official body which takes the official country-by-country
votes on these recommendations.  They are then forwarded
to upper level ISO groups (JTC1, etc.) for further
even-more-official action.

All of our activities are quite open.  The ada-auth site
mentioned above is the best place to look for minutes,
technical reports, Ada Interpretations (AIs), etc.

I agree with all of the above.  Note that there are test suites
for other languages which are publically available, but the
Ada test suite (officially called the "Ada Conformity
Assessment Test Suite" -- ACATS) has an official status
with respect to the ISO standardized Ada conformance
testing process.  Also, the test suite is under continuous
maintenance by the ACAA (Ada Conformity Assessment Authority),
to ensure that it always reflects the latest rulings of
WG9.

Although in the beginning, the Ada test suite was a royal
pain for implementors, it is now clear that to achieve
true standardization, a rigorous test suite that is
widely available is essential.  My own view is that part
of the failure of Java on the client was the inadequacy
and lack of easy availability of a rigorous test suite
for Java (especially for the GUI/AWT libraries).

Sun is still pretty stingy with their test suites, though
we are at least now seeing more visibility of "J2EE
certification."  This seems like one of the few test suites
that has achieved the level of visibility to the average
users that the Ada test suite has had in the Ada community.

But popular language *implementations* have never been tested by such
testing centers. ;-) (Or maybe they have been tested, but the results
where too embarrassing to be published.)
