This enumerated list defines where within a record the indexed data values reside. Indexes can be constructed on attributes or on fields within the opaque object in the record. CSSM_DB_INDEX_ON_UNKNOWN indicates that the logical location of the index value between these two categories is unknown.

typedef enum cssm_db_indexed_data_location {
    CSSM_DB_INDEX_ON_UNKNOWN = 0,
    CSSM_DB_INDEX_ON_ATTRIBUTE = 1,
    CSSM_DB_INDEX_ON_RECORD = 2
