Slot: uniqueKey

Unordered set of Items whose combined values uniquely identify a record in this dataset (the record key). Each entry is an OID reference to an Item in the items array. Order is not significant for uniqueness — use keySequence for sort order. Splitting uniqueness from sorting resolves the previous overloading of keySequence.
