Only one record with the same identifierSchemeId (field) and alternateIdentifier (field) fields will be current at any point in time. The current record will be the one with the most recent effectiveTimebefore effectiveTime before or equal to the point in time under consideration.

If thefield of this record is false ('0'), then the association isat that point in time. If thefield is true ('1'), then there is an identity at that point in time between the referencedComponentId (field) (a) and the alternateIdentifier in the scheme identified by identifierSchemeId (field).
