The "Response Policy Zone (RPZ) Rewriting" section Chapter 6, "BIND 9
Configuration Reference" of the ARM, the Administrator's Reference Manual,
says in part:

] The policies specified in individual records in an RPZ can be
] overridden with a policy clause in the response-policy option. An
] organization using an RPZ provided by another organization might
] use this mechanism to redirect domains to its own walled garden.
] ...
] 	CNAME domain causes all RPZ policy records to act as if
] 	they were "cname domain" records.
