ElementConstraints:
Signature: multiplicity() : Boolean;
Description: The multiplicity of ExtensionEnd is 0..1 or 1.
Expression: (self->lowerBound() = 0 or self->lowerBound() = 1) and self->upperBound() = 1
Signature: aggregation() : Boolean;
Description: The aggregation of an ExtensionEnd is composite.
Expression: self.aggregation = #composite
Operations:
Signature: lowerBound() : Integer;
Description: The query lowerBound() returns the lower bound of the multiplicity as an
Integer. This is a redefinition of the default lower bound, which normally,
for MultiplicityElements, evaluates to 1 if empty.
The OCL used here is not normative.Editor's notes: removed lowerBound = ... but IntegerValue is not defined
Expression: 1
Original: result = lowerBound = if lowerValue->isEmpty() then 0 else lowerValue->IntegerValue() endif
