Sure, you can do this, but not with just one zone file.  You will need
two zone definitions in your named.conf.  Something like:

    zone "example.com" {
        type master;
        file "/usr/local/etc/namedb/master/example.com";
        allow-query {
            any;
        };
        allow-transfer {
            secondaries;
        };
    };

    zone "foo.example.com" {
	type "slave";
	masters {
	    192.0.2.1;
	};
	allow-query {
	    any;
        };
    };

But you will definitely need separate zone files for the parent and
child domains.  That's the only way you can have one as primary and the
other as a secondary.  However, when BIND is acting as the secondary it
just transfers the zone data from the primary, and you don't have to do
anything to that file other than provide space for it in your filesystem.

Consult the Bind9 ARM for the details of what you can put into zone
definitions.  Also remember you need to delegate the sub-zone to
whatever nameservers you're using by adding suitable NS records in your
zone data.

	Cheers,
