The CHANNELS: section specifies the words that make up a human-readable representation of the HANDLE VIA... handling caveats that must be included in printer banner pages. This section is used by the system only to translate the internal form of sensitivity labels to the appropriate human-readable handling channel caveat. The example in Printed Banner Example Denoting Channels String shows the format of a printer banner page with the handling channel caveat denoted. Since this section is not used for translating human-readable handling caveats into the internal format, there is no need for the REQUIRED COMBINATIONS: and COMBINATION CONSTRAINTS: subsections. Therefore, the CHANNELS: section contains a single subsection: WORDS:.
The CHANNELS: WORDS: subsection has a structure similar to the SENSITIVITY LABELS: WORDS: subsection. However, the sname=, iname=, minclass=, and maxclass= keywords have no meaning or purpose for handling caveats, and are therefore ignored.
In all cases, the CHANNELS: section cannot associate words with compartment bits not associated with words in the INFORMATION LABELS:, SENSITIVITY LABELS:, and CLEARANCES: sections.
