The HasInterlock ReferenceType is a concrete ReferenceType that can be used directly. It is a subtype of the HasComponent ReferenceType.
The semantic is a part-of relationship. Figure 16 provides an illustration of how this ReferenceType is used. Multiple SourceNodes can reference the same TargetNode and a SourceNode can reference multiple TargetNodes.
Like all other ReferenceTypes, this ReferenceType does not specify anything about the ownership of the parts, although it represents a part-of relationship semantic. That is, it is not specified if the TargetNode of a Reference of the HasInterlock ReferenceType is deleted when the SourceNode is deleted.
The TargetNode of this ReferenceType shall be the InterlockVariableType or a Variable of InterlockVariableType or a subtype of InterlockVariableType.
The SourceNode shall be an instance of MDISChokeObjectType or MDISValveObjectType or a subtype of MDISAggregateObjectType that is being used for aggregation or one of these ObjectTypes.

The InterlockFor ReferenceType is a concrete ReferenceType and can be used directly. It is a subtype of NonHierarchicalReferences. The inverse reference shall also exist for all uses of this ReferenceType.
The semantic of this ReferenceType is to relate InterlockVariableType Nodes to the Variable Node that represents an interlock flag.
The SourceNode of this ReferenceType shall be an instance of InterlockVariableType.
The TargetNode of this ReferenceType shall be a Variable that is one of NonDefeatableOpenInterlock, DefeatableOpenInterlock, NonDefeatableCloseInterlock or DefeatableCloseInterlock. The Variable shall be part of an MDISValveObjectType or MDISChokeObjectType or MDISAggregateObjectType, a subtype of one of these types or an instance of one of these types.

The HasSignature ReferenceType is a concrete ReferenceType that can be used directly. It is a subtype of the HasComponent ReferenceType.
The semantic is a part-of relationship. Figure 20 provides an illustration of how this ReferenceType is used. A TargetNode can be referenced by a single SourceNode and a SourceNode can reference multiple TargetNodes.
Like all other ReferenceTypes, this ReferenceType does not specify anything about the ownership of the parts, although it represents a part-of relationship semantic. That is, it is not specified if the TargetNode of a Reference of the HasSignature ReferenceType is deleted when the SourceNode is deleted.
The TargetNode of this ReferenceType shall be an instance of FileType. The FileType instance shall contain valve signature information.
The SourceNode shall be an instance of MDISValveObjectType or a subtype of MDISValveObjectType. It might also be a MDISChokeObjectType or any other MDIS ObjectType that might need to report a signature.
