  • Key: UML22-176
  • Legacy Issue Number: 9237
  • Status: closed  
  • Source: NIST ( Mr. Conrad Bock)
  • Summary:

    Can an instance specification for a classifier specify instances of subtypes of the classifier? For example, if Fido is an instance specification for Class Dog, can the runtime object it specifies be an instance of Terrier?

  • Disposition: Resolved — UML 2.2
  • Disposition Summary:

    An InstanceSpecification can be partial. The spec is quite clear about this. It is also clear that every slot
    must correspond to a feature of one of the classifiers. If the InstanceSpecification is classified as a Dog, it
    might be a Terrier at runtime but you have no way to know that. Insert some text to make this clear.
