I have a question regarding include use cases. According to the SysML v2 Specification, an include use case is both a kind of use case and a kind of perform action.

I attempted to construct a model in which a part contains two part features, namely Part1 and Part2, and the part also contains an include use case. Since an include use case is defined as a perform action, when I select the part and choose “Show Swim Lane”, I expected to see Part1 and Part2 represented as swim lanes. However, the result only shows the subject and actors of the use case.

I am unsure whether this behavior is consistent with the intended interpretation of the specification, or whether the notion that an include use case is a perform action is meant to refer to something else.
