[about multi-part ISO standards]

At present, Ada is a single standard, ISO/IEC 8652/1995(E) with
Technical Corrigendum 1 and Amendment 1. Since Amendment 1, this
single-part standard incorporates and supersedes another standard, ISO
13813:1997 (linear algebra). So, the answer to your question is no.
See however the recent call for participation in a possible update to
ISO 14519, the Ada POSIX binding. POSIX is a multi-part standard.
The Rapporteur for the Ada POSIX bindings said that one option would
be to incorporate the Ada POSIX bindings into the Ada standard under
Ada.Interfaces, but he did not say whether splitting ISO 8652 into
several parts was desirable.

In the past, despite being a monolithic standard, Ada has achieved the
effects of multi-part standards by placing ASIS and the linear algebra
in separate standards (ISO/IEC 15291:1999 and ISO/IEC 13813:1997
respectively). Apparently, that has not helped shorten the revision
cycle for the language definition, so I think that the problem lies
elsewhere.
I think that multi-part standards work best when the working group is
so large that it can split into sub-groups effectively. I don't think
that that's the case for WG9. In fact, the main problem in WG9 is
lack of manpower; that's why they decided to publish Ada 2005 as an
Amendment to, rather than a new Edition of the standard.
