Because there is no other way to tell. No one is going to implement it (or
put it into the Standard) unless they know that it is "at least as
compatible as an existing Ada implementation". You're going to have to prove
that somehow, and that proof is going to have to be at least semi-formal,
because it is going to have to be convincing. Handwaving in a forum like
this is not a convincing proof.
