A CONSTRAINT can be a predicate. However :

a) what is the meaning of something like
a = 10 /\ (true = false)

b) the bparser has several predicate levels (thanks to J.Dick ;). So we can have the BNF rule (which is more precise)

Constraints : B_CONSTRAINTS PredLevel2

c) constraint like the following
maxvalue < 123456

was rejected by barser (not the adequate predicate level) but accepted by AB (of course).

=> Seems that b) will/should be applied in the bparser.
