do I have this wrong?

If I should not be sending this to this list please let me know.  
Please let me know if you think I have this wrong:

Bare Minimum to be considered a usable DNS server (under limited  
conditions):

When a zone is configured locally as a master or slave zone, only hand  
out data from the local configuration. Do not accept records in that  
zone into the cache that come from another server. Never hand out data  
in that zone received from another server.

Desired Behavior to be considered a good working DNS server:

In addition to the above:

When a zone is configured locally as a stub zone, only accept into  
cache records in that zone from the zone's name servers as configured  
in the stub zone. Never hand out data from that zone unless it was  
received from one of the zone's name servers.

When a zone is configured locally as a forward zone, only accept  
records in that zone into the cache that come from the servers to  
which the zone was specified to be forwarded. Never hand out data from  
that zone unless it was received from one of the forwarders.

Thanks,
Maria
