Starting an Action that has a ControlPin
Notes
Snippets (quotes/extracts)
  [UML-2.5.1] An Action may accept inputs and produce outputs, as specified by InputPins and OutputPins of the Action, respectively. Each Pin on an Action specifies the type and multiplicity for a specific input or output of that Action.
  [UML-2.5.1] An Action cannot start execution if one of its InputPins has fewer values than the lower multiplicity of that InputPin.
  [UML-2.5.1] When completed, an Action execution provides any output data on the OutputPins of the Action, and it terminates.
  [UML-2.5.1] The Action execution consumes input data on all InputPins on the Action up to the upper multiplicity for each InputPin.
  [UML-2.5.1] Tokens consumed by an Action are immediately removed from its InputPins when the action begins an execution (except in some cases for StructuredActivityNodes, where tokens may remain on InputPins during the Action execution ...)
  [UML-2.5.1] The upper multiplicity determines the maximum number of values that can be consumed from an InputPin by a single execution of its Action.
  [UML-2.5.1] 16.4.3.5 Value Specification Actions - A ValueSpecificationAction is an Action that evaluates a ValueSpecification and places the resulting value on its result OutputPin.
