The COMPONENT_RELATIONSHIP_ELEMENT class is an ELEMENT whose coded meaning is constrained to represent an asserted relationship
between two other RECORD_COMPONENTs. The association role links collection is therefore constrained to two member LINKs,
one of which references the subject RECORD_COMPONENT and the other the object.
Because the COMPONENT_RELATIONSHIP_ELEMENT is a RECORD_COMPONENT in its own right, it can be asserted, revised or maintained
separately from both the related RECORD_COMPONENTs.
