Constraints:

Signature: unlimited_natural() : Boolean;
Description: Actions removing a value from ordered non-unique variables must have a single removeAt input pin and no value input pin if isRemoveDuplicates is false. The removeAt pin must be of type Unlimited Natural with multiplicity 1..1. Otherwise, the action has a value input pin and no removeAt input pin.
Expression: if not self.variable.isOrdered or self.variable.isUnique or isRemoveDuplicates then self.removeAt -> isEmpty() and self.value -> notEmpty() else self.value -> isEmpty() and self.removeAt -> notEmpty() and self.removeAt.type = UnlimitedNatural and self.removeAt.lower() = 1 and self.removeAt.upper() = 1 endif

No additional operations.
