Bind 9 strict zones

[Kvetch]

Hello, we are upgrading our DNS server from BIND 8 to 9 but we have
noticed that we have some issues with our zone configuration.  We see
that if we had a zone called db.bar with entries for bar.net and
foo.bar.net everything is fine but if we had a 4th level record in the
same zone this is no longer valid in BIND9 and we would need a
seperate zone.  I know this is the correct way to do this but is there
a work so we could have bar.net and foo.bar.net AND test.foo.bar.net
in the bar.net zone?
So is there a way to do the following within the same zone in BIND 9?
localhost       IN      A       127.0.0.1
@                 IN      A       192.168.1.1
www             IN      A       192.168.1.1
foo                IN      A        192.168.1.2
test.foo.bar    IN      A       192.168.1.3

Thanks,
Nick
