Open Closed All

  • Summary:

    To put it simply, I'm saying this:

    The spec should clearly state that an instance spec is a legitimate value
    of a property typed by a classifier.
    The spec should make sure that the abstract syntax operations &
    constraints involving all kinds of UML classifiers & instance
    specifications work according to the above.

    The UML spec tacitly agrees with this as shown in several examples:

    Figure 7.54 in UML 2.4.1, page 82.
    Figures 9.31, 9.32, 9.33 in UML Simplification Revised August draft, p. 143

  • Disposition Summary:

    A legitimate value of a property (actually a Slot) is an InstanceValue, which is what is depicted by figures 9.32 and
    9.33.
