for C being initialized standardized ConstructorSignature
for e being expression of C holds
( ( (e . {}) `1 in Vars & (e . {}) `2 = a_Term & e is quasi-term of C ) or ( (e . {}) `2 = the carrier of C & ( ( (e . {}) `1 in Constructors & (e . {}) `1 in the carrier' of C ) or (e . {}) `1 = * or (e . {}) `1 = non_op ) ) )
