The HasSubStateMachine ReferenceType is a concrete ReferenceType and can be used directly. It is a subtype of NonHierarchicalReferences.

The semantic of this ReferenceType is to point from a State to an instance of a StateMachineType which represents the sub-states for the State.

The SourceNode of this ReferenceType shall be an Object of the ObjectType StateType. The TargetNode shall be an Object of the ObjectType StateMachineType or one of its subtypes. Each Object can be the TargetNode of at most one HasSubStateMachine Reference.

The SourceNode (the state) and the TargetNode (the SubStateMachine) shall belong to the same StateMachine. Therefore, the SourceNode shall be referenced from the ObjectType FiniteStateMachineType or one of its subtypes and the TargetNode shall be referenced from the same ObjectType, both using a HasComponent Reference or a subtype of HasComponent.

The representation of the HasSubStateMachine ReferenceType in the AddressSpace is specified in Table 14.
