Signal Creation Action asynchronously creates instance of exactly one Class

Class has instance asynchronously created by zero, one or many Signal Creation Action

---

A Signal Creation Action will trigger a creation event defined on a single Class, resulting in a new instance of that Class.

Any given Class may or may not define such a creation event. If not, it will never receive a creation signal.

And even if a creation event is defined on a Class, no Signal Creation Action may be defined to send the corresponding Signal. This would likely be due to an incompletely defined model.

More than one Signal Creation Action could be defined in various Activities scattered throughout a model, all targeting the same Class.

Formalization

Signal Creation Action.(Class, Domain) -> Class.(Name, Domain)
