States of a FiniteStateMachine are represented as Objects of the StateType. Each Object of the StateType or one of its subtypes shall be referenced from the ObjectType FiniteStateMachineType or one of its subtypes using a HasComponent Reference or a subtype of HasComponent and shall not have a ModellingRule as they are not applied on the instances.
The StateType is formally defined in Table 7.
