6.3 AASReferenceType

For AAS references as used in ReferenceElement of RelationshipElement a new non-hierarchial ReferenceType “AASReference” is introduced (Figure 9). The OPC UA ReferenceType 0:HasComponent is not directly used to reference an element because OPC UA references can only reference elements in the same address space. For more details please see rule 24 in section 5.1.
