R834 / Generalization

State Activity is a Lifecycle Activity, Single Assigner Activity, or Multiple Assigner Activity

---

The Actions available in a State Activity depend on the type of State Model.

For example, a Single Assigner specifies the management of competition on an Association. It is not associated with any instance so, for example, relationship traversal cannot be specified from an unqualified instance (self). You can specify this, however, for any Lifecycle state since you always have an executing instance to initiate the traversal path.
