multiple `zone' clauses for a single domain?

[Marek Kozlowski]

:-)
Forgive me a stupid question but I can't find the answer...

Is it allowed to use a few `zone' clauses for a single domain? Is
something like this correct:

zone "mickey.mouse.com" in {
        type master;
        file "pri/mickey-public.zone";
        allow-query { any; };
        allow-transfer { xfer; };
};

zone "mickey.mouse.com" in {
        type master;
        file "pri/mickey-private.zone";
        allow-query { trusted; };
        allow-transfer { xfer; };
};

where `mickey-public.zone' stores information on public hosts from my
domain while `mickey-private.zone' stores hosts that should be
visible/known only for trusted host?

Should I duplicate all records from `mickey-public.zone' in
`mickey-private.zone'?

Do I *have* to use views to deal with such distinction or can I specify
it just as above without views?

Best regards,
Marek
