The semantic of this ReferenceType is to point form a Transition to the ending State the Transition connects.

The SourceNode of this ReferenceType shall be an Object of the ObjectType TransitionType or one of its subtypes. The TargetNode of this ReferenceType shall be an Object of the ObjectType StateType or one of its subtypes.

References of this ReferenceType may be only exposed uni-directional. Sometimes this is required, for example, if a Transition points to a State of a sub-machine.
