 * A human-friendly name for a security context ID can be registered with

 * description and not to actually dissect anything.
 *
 * BPSec per-context parameter types and result types are registered with the
 * dissector table "bpsec.param" and "bpsec.result" respectively.
 * Both use bpsec_id_t* table keys, to identify both the context and the type
 * code points.
