To provide the capacity for the largest number of values in the smallest space, non-hierarchical constraint values are defined in RLS tables as bit positions rather than as numeric values. The bit positions are represented in the table as hex code.

The method by which hex-encoded constraint values are loaded into an RLS table varies depending on the presence or absence of the OVERRIDE privilege.
