How many NS records should be in the 0.0.127.in-addr.arpa zone?

Setup is BIND 8.2.1 on a mix of RedHat Linux 5.1 and HP-UX 10.20. Internal
DNS with forwarders to resolve Internet domain names and addresses.
According to the DNS and BIND book the zone file for 0.0.127.in-addr.arpa
should contain an NS record for each server in your domain (see the 3rd
edition page 67). First question - is this a correct assumption?
The reason I ask is that when named starts it sends a NOTIFY for each
primary zone to the name servers identified by the NS records (except itself
of course). I got to thinking that the 0.0.127.in-addr.arpa zone will have
notify requests sent to my secordary name servers which will get ignored as
they aren't secondarying 0.0.127.in-addr.arpa. Second question - am I still
on track here?
So to my mind (and as far as DNS goes it's a pretty small mind :-) I reckon
that the only NS record in the zone file for 0.0.127.in-addr.arpa zone
should be for the name server the db.127.0.0 file resides on. Third
question - is this correct or will I break something by doing so?
Thanks in advance,
