Subactivities

Subactivities represent nested activity diagrams.

Subactivities represent the execution of a non-atomic sequence of steps of some duration nested within another activity. Internally, a subactivity consists of a set of actions, and possibly a wait for events. In other words, a subactivity is a hierarchical action during which an associated subactivity diagram is executed. Therefore, a subactivity is a submachine state that executes an activity diagram.
