Constraints:

Signature: type_is_classifier() : Boolean;
Description: The type of the result output pin is the classifier.
Expression: true

Signature: multiplicity_of_result() : Boolean;
Description: The multiplicity of the result output pin is 0..*.
The OCL used here is not normative.
Editor's notes: No multiplicity. UnlimitedNatural literal needs investigation.
Expression: true
Original: self.result.multiplicity.is(0,#null)

Operations:

No additional operations.
