  4.4.12 FromState
  FromState The FromState 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 Transition ... Object of the ObjectType StateType or one of its subtypes. The representation of the FromState ReferenceType in the AddressSpace is specified in Table 12 . Table 12 - FromState ReferenceType Attributes Value

  State for a Transition is a StateType Object which is the target of a FromState Reference . The final State for a Transition is a StateType Object which is the target ... ToState Reference . The FromState and ToState References shall always be specified. A Transition may produce an Event . The Event is indicated by a HasEffect Reference to a subtype of BaseEventType
