False error in DNSSEC10 on a zone with a wildcard below apex

[matsduf]

When testing personeelsrecht.nu an error is reported in DNSSEC10, but the error does not match the behavior of the zone. The implementation should not returned DS10_MISSING_NSEC_NSEC3 in this case.

There is another issue on DNSSEC10, but on the specification (zonemaster/zonemaster#1153). They are related in so far as the both hit zones with wildcard below apex.

This issue should wait for the specification to be adjusted.
