When you include DNSKEYS with multiple algorithms, both the DNSKEY RRset and
other RRsets in the zone must be signed with each algorithm . Because
you designed your RSASHA256 DNSKEY as a KSK, dnssec-signzone is only using
it to sign the DNSKEY RRset, not other RRsets. To resolve this, create a
ZSK with algorithm RSASHA256 to your zone.
