UML22 — UML 2 Super/templates/inexplicable constraint on defaults

Open Closed All
  • Key: UML22-762
  • Legacy Issue Number: 8264
  • Status: closed  
  • Source: Simula Research Laboratory ( Dr. Bran Selic)
  • Summary:

    The definition of TemplateParameter states that the parameter cannot own at the same time its parametered element and default element. The ownership of those two elements is mutually exclusive. It is also expressed as an OCL constraint. However, there is no justification offered in the spec for this constraint and one is not obvious. The constraint should be removed.

    Indeed, cannot see any justification for this. Remove the constraint.
