03831d35f7499c87d51205817c93e9a8d42c4baestevel verifies that a zone is fully signed for each algorithm found
03831d35f7499c87d51205817c93e9a8d42c4baestevel in the DNSKEY RRset for the zone, and that the NSEC / NSEC3
03831d35f7499c87d51205817c93e9a8d42c4baestevel chains are complete.

03831d35f7499c87d51205817c93e9a8d42c4baestevel When BIND is built with OpenSSL PKCS#11 support, this defaults
03831d35f7499c87d51205817c93e9a8d42c4baestevel to the string "pkcs11", which identifies an OpenSSL engine
03831d35f7499c87d51205817c93e9a8d42c4baestevel that can drive a cryptographic accelerator or hardware service
03831d35f7499c87d51205817c93e9a8d42c4baestevel module. When BIND is built with native PKCS#11 cryptography
03831d35f7499c87d51205817c93e9a8d42c4baestevel (--enable-native-pkcs11), it defaults to the path of the PKCS#11

03831d35f7499c87d51205817c93e9a8d42c4baestevel This option is primarily intended to be used for dynamic
03831d35f7499c87d51205817c93e9a8d42c4baestevel signed zones so that the dumped zone file in a non-text

03831d35f7499c87d51205817c93e9a8d42c4baestevel The use of this option does not make much sense for

Only verify that the DNSKEY RRset is signed with key-signing
keys. Without this flag, it is assumed that the DNSKEY RRset
will be signed by all active keys. When this flag is set,
it will not be an error if the DNSKEY RRset is not signed
by zone-signing keys. This corresponds to the <code class="option">-x</code>

Ignore the KSK flag on the keys when determining whether
the zone if correctly signed. Without this flag it is
assumed that there will be a non-revoked, self-signed
DNSKEY with the KSK flag set for each algorithm and
that RRsets other than DNSKEY RRset will be signed with
a different DNSKEY without the KSK flag set.
</p>
<p>
With this flag set, we only require that for each algorithm,
there will be at least one non-revoked, self-signed DNSKEY,
regardless of the KSK flag state, and that other RRsets
will be signed by a non-revoked key for the same algorithm
that includes the self-signed key; the same key may be used
for both purposes. This corresponds to the <code class="option">-z</code>
