it's nsd-3.2.6 build from source an ldnsutils 1.6.5 
to be precise: the zone in question is "t-isa.de"

the zonefile:
--- snip
$TTL 1d

t-isa.de.                                       SOA     (
        nsd01.t-isa.de. hostmaster-soa.datev.de. 2010110902 4h 4444s 40d 40m )
t-isa.de.                                       NS      nsd01.t-isa.de.
t-isa.de.                                       NS      nsd02.t-isa.de.
t-isa.de.                       300             MX      0 mailin11.t-isa.de.

t-isa.de.                                       TXT     "v=spf1 ip4=193.27.48.0/21 -all"
t-isa.de.                                       SPF     "v=spf1 ip4=193.27.48.0/21 -all"

nsd01.t-isa.de.                                 A       193.27.50.9
nsd02.t-isa.de.                                 A       193.27.54.9

...
--- snap

and thats what "ldns-read-zone t-isa.de" prints out:
t-isa.de.       86400   IN      SOA     nsd01.t-isa.de. hostmaster-soa.datev.de. 2010110902 14400 4444 3456000 2400
t-isa.de.       86400   IN      NS      nsd01.t-isa.de.
t-isa.de.       86400   IN      NS      nsd02.t-isa.de.
t-isa.de.       300     IN      MX      0 mailin11.t-isa.de.
t-isa.de.       300     IN      TXT     "v=spf1 ip4=193.27.48.0/21 -all"
t-isa.de.       300     IN      SPF     "v=spf1 ip4=193.27.48.0/21 -all"
nsd01.t-isa.de. 300     IN      A       193.27.50.9
nsd02.t-isa.de. 300     IN      A       193.27.54.9
...

up to this point only ldns is involved.
next players are ldns-signzone and zonec.
public verifyable is this:

$ dig @nsd01.t-isa.de t-isa.de any +noall +answer| grep -v DNSKEY | grep -v RRSIG

t-isa.de.               86400   IN      SOA     nsd01.t-isa.de. hostmaster-soa.datev.de. 2010110902 14400 4444 3456000 2400
t-isa.de.               86400   IN      NS      nsd01.t-isa.de.
t-isa.de.               86400   IN      NS      nsd02.t-isa.de.
t-isa.de.               300     IN      MX      0 mailin11.t-isa.de.

t-isa.de.               3600    IN      TYPE51  \# 5 0100000100
