Description :
The ACSL grammar has declarations: //@ predicate a; and definitions //@ predicate a = \true;
The current grammar requires declarations to be in an axiomatic. However the current implementation in Frama-C allows both definitions and declarations both at global scope and within axiomatics.
I propose changing the ACSL documentation/grammar to match current behavior.
Similarly axioms should be allowed both inside and outside axiomatics.
