Planning the Compartment Values and Combination Constraints in a Worksheet

The following table defines the relationships between words and classifications. The relationships were determined by using the planning board in Figure 6–4. PUBLIC and INTERNAL_USE_ONLY can never appear in a label with any compartment. NEED_TO_KNOW can appear in a label with any of the compartments or all of the compartments. The classification and compartment values are listed in ascending bit order.
