[CentOS] External view in sample BIND named.conf

I just want to confirm that this is a "bug" before reporting it to Bugzilla.

I started with the sample named.conf included in the distribution and found 
that I couldn't query my server from outside my LAN. I finally traced it 
down to the match expressions in the sample's external view.

bind-9.3.3-9.0.1.el5
/usr/share/doc/bind-9.3.3/sample/etc/named.conf

The view has these match settings:

        match-clients           { !localnets; !localhost; };
        match-destinations      { !localnets; !localhost; };

Changing these to "any" allowed queries to get in.

Is the ! syntax invalid for this version of BIND?

I don't see anything in Buzilla that looks like this issue:
