SMOF_ — Compatiblity constraints and instances

  • Key: SMOF_-13
  • Legacy Issue Number: 17154
  • Status: closed  
  • Source: NIST ( Conrad Bock)
  • Summary:

    Section (Compatibility), Semantics, should clarify whether
    instances can be taken into account when evaluating the constraint
    specification (compare to the AspectOf, Attributes, isRequired, next to
    last paragraph in the description). If they can, the last sentence
    presumably should replace evaluates to true" with "evaluates to true for
    all possible instances of either type". My understanding is the
    Compatible constraint specification must evaluate to true for an
    instance to be classified under both types, so if the constraint spec
    can account for instances, then all instances (past, present, and
    future) of both types must satisfy the constraint spec for the types to
    be equivalent.
