	// The state of DNSSEC on the zone.
	// For DNSSEC to function, every parent zone in the DNS tree up to the top-level domain (or an independent
	// trust anchor) must also have DNSSEC correctly set up.
	// After enabling DNSSEC, you must add a DS record to the zone's parent zone containing the
	// `KskDnssecKeyVersion` data. You can find the DS data in the `dsData` attribute of the `KskDnssecKeyVersion`.
	// Then, use the `PromoteZoneDnssecKeyVersion` operation to promote the `KskDnssecKeyVersion`.
	// New `KskDnssecKeyVersion`s are generated annually, a week before the existing `KskDnssecKeyVersion`'s expiration.
	// To rollover a `KskDnssecKeyVersion`, you must replace the parent zone's DS record containing the old
	// `KskDnssecKeyVersion` data with the data from the new `KskDnssecKeyVersion`.
	// To remove the old DS record without causing service disruption, wait until the old DS record's TTL has
	// expired, and the new DS record has propagated. After the DS replacement has been completed, then the
	// `PromoteZoneDnssecKeyVersion` operation must be called.
	// Metrics are emitted in the `oci_dns` namespace daily for each `KskDnssecKeyVersion` indicating how many
	// days are left until expiration.
	// We recommend that you set up alarms and notifications for KskDnssecKeyVersion expiration so that the
	// necessary parent zone updates can be made and the `PromoteZoneDnssecKeyVersion` operation can be called.
	// Enabling DNSSEC results in additional records in DNS responses which increases their size and can
	// cause higher response latency.
	// For more information, see DNSSEC (https://docs.oracle.com/iaas/Content/DNS/Concepts/dnssec.htm).
