hint zone or forward ?

[cmic]

Hello.
I am using Bind 9.3.1 under Linux for a private zone "dom.prv"
in which clients cannot resolve anything but "dom.prv"
But now I want the clients to be able resolve another private
zone named "iq". I solved the problem by inserting this
in my named.conf (i think the rest of named.conf is of no use
for the matter...)
...
zone "." {
        type hint;
        file "interne/db.root";
};
...

And the db.root file is :

@       0       SOA     iq admin\server.iq (
                2006090201 ; serial
                1H ; refresh
                2H ; retry
                4W ; expire
                1D ) ; minimum
;
                IN      NS      ns.iq.
ns.iq		IN      A       172.21.16.254


It works as expected:  The commands 'host abc.dom.prv' and
'host macine.sub.iq' both yieds correct answers, but I wonder if
the hint zone is the correct (elegant?) way to solve this problem.
I thought forward & forwarders would have been a better
solution, but i can't make it work.

Any advice ?
TYA
