   They do, but the process is still slow and deliberate.  During the
(officially just over eleven years) between Ada 83 and Ada 95, there
were a half-dozen cases where the Ada Rapporteur Group issued Nonbinding
interpretations, one of them on raising Contstraint_Error instead of
Program_Error.  The goal of these NBIs was to allow implementors to
move in the direction that the new language revision would move
without forcing any particular schedule.  In cases where the language
was unclear but all compilers behaved consistantly, we enforced the de
facto standard with binding interpretations.

   The official process with Ada 95 may be somewhat different since we
intend to issue corrigenda consolidating the AIs, but the results
should be the same--a slow evolution in the definition of the
language.
