The execution of an action represents some transformation or processing in the modeled system, be it a computer system or otherwise.

Properties:

context : Classifier (0 1); -- source Action

The classifier that owns the behavior of which this action is a part.
{readonly, derived}
The spec does not provide a function to compute this derived property!
