> RFC 2308 "DNS NCACHE" defines the last field of the SOA RR as "the TTL of

Negative caching TTL is not defined as the last field of the SOA RR:
"When the authoritative server creates this record its TTL
is taken from the minimum of the SOA.MINIMUM field and SOA's TTL."

Because minimum is what it is? It's not negative caching ttl, see above.
