Table 5-3 defines the relationships between words and classifications that were arrived at by moving things around on the planning board in Figure 5-7. Because of how PUBLIC and INTERNAL_USE_ONLY are defined in the third column, these two classifications can never appear in a label with any compartment, while NEED_TO_KNOW can appear in a label with any or all of the compartments.
