One of these DNSKEY RRs also has the SEP flag set and has been used to sign the apex DNSKEY RRset; this is the key that should be hashed to generate a DS record to be inserted into the parent zone. The other DNSKEY is used to sign all the other RRsets in the zone. The zone includes a wildcard entry, "*.w.example". Note that the name "*.w.example" is used in constructing NSEC chains, and that the RRSIG covering the "*.w.example" MX RRset has a label count of 2. The zone also includes two delegations. The delegation to "b.example" includes an NS RRset, glue address records, and an NSEC RR; note that only the NSEC RRset is signed. The delegation to "a.example" provides a DS RR; note that only the NSEC and DS RRsets are signed.
