## B.4.14 HasEffect

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

The semantic of this ReferenceType is to point form a Transition to something that will be effected when the Transition is triggered. In this annex we only define EventTypes as Effects. However, the ReferenceType is not restricted to point to EventTypes.

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

The representation of the HasEffect ReferenceType in the AddressSpace is specified in Table B.13.
