And *all* keys that support NSEC3 are also NSEC capable. There
isn't such a thing as a NSEC3 key. There are NSEC3 capable keys
and keys that are not NSEC3 capable. All keys are NSEC capable.
As for the NSEC3PARAM going away it is only supposed to exist in a
*signed* zone and you are attempting to add it to a unsigned zone.
The key timing are there for managing keys in a already signed zone.
You are attempting to use them to start signing the zone which
requires as whole different set of steps to be done.
To get named to convert a unsigned zone to a signed zone with NSEC3
use nsupdate to add the DNSKEYs and NSEC3PARAM record in the same
