R840 / Generalization

State Activity is a Real State Activity or Delegated Creation Activity

---

All modeler specified state activities are Real State Activities. Basically, what we usually mean when we talk about a state activity. Delegated Creation Activities are special since they are generated automatically from information supplied by an action. That action is an Initial Signal Action which directs a class to create a new instance asynchronously.

The same rules of execution, however, apply to any State Activity, so from an execution perspective, there's no distinction.
