 *
 * DST_KEY_STATE_HIDDEN:      Records of this type are not published in zone.
 *                            This may be because the key parts were never
 *                            introduced in the zone, or because the key has
 *                            retired and has no records of this type left in
 *                            the zone.
 * DST_KEY_STATE_RUMOURED:    Records of this type are published in zone, but
 *                            not long enough to ensure all resolvers know
 *                            about it.
 * DST_KEY_STATE_OMNIPRESENT: Records of this type are published in zone long
 *                            enough so that all resolvers that know about
 *                            these records, no longer have outdated data.
 * DST_KEY_STATE_UNRETENTIVE: Records of this type have been removed from the
 *                            zone, but there may be resolvers that still have
 *                            have predecessor records cached.  Note that RRSIG
 *                            records in this state may actually still be in the
 *                            zone because they are reused, but retired RRSIG
 *                            records will never be refreshed: A successor key
 *                            is used to create signatures.
 * DST_KEY_STATE_NA:          The state is not applicable for this record type.
