And the gory details from the ARM.

5.9.4. Private-type records

The state of the signing process is signaled by private-type records (with a 
default type value of 65534). When signing is complete, these records will have 
a nonzero value for the final octet (for those records which have a nonzero 
initial octet).

The private type record format: If the first octet is non-zero then the record 
indicates that the zone needs to be signed with the key matching the record, or 
that all signatures that match the record should be removed.

algorithm (octet 1)

key id in network order (octet 2 and 3)

removal flag (octet 4)

complete flag (octet 5)

Only records flagged as “complete” can be removed via dynamic update. Attempts 
to remove other private type records will be silently ignored.

If the first octet is zero (this is a reserved algorithm number that should 
never appear in a DNSKEY record) then the record indicates changes to the NSEC3 
chains are in progress. The rest of the record contains an NSEC3PARAM record. 
The flag field tells what operation to perform based on the flag bits.
