  • Key: UML25-414
  • Legacy Issue Number: 18049
  • Status: closed  
  • Source: Soluta.net ( Adriano Comai)
  • Summary:

    current text: “The behaviors of a UseCase can be described by a set of Behaviors (through its ownedBehavior relationship), such as Interactions, Activities, and StateMachines, or by pre-conditions and post-conditions...”

    [AC] The “or” in “ or by pre-conditions and post-conditions” is ambiguous, because it can be interpreted as an XOR, while it is not exclusive. In fact, but several lines below, it is correctly stated that “These descriptions can be combined”. I suggest to remove the “or”.
