+         The <command>nxdomain-redirect</command> option specifies
+         a DNS namespace to use for NXDOMAIN redirection. When a 
+         recursive lookup returns NXDOMAIN, a second lookup is
+         initiated with the specified name appended to the query
+         name. This allows NXDOMAIN redirection data to be supplied
+         by multiple zones configured on the server or by recursive
+         queries to other servers. (The older method, using
+         a single <command>type redirect</command> zone, has
+         better average performance but is less flexible.) [RT #37989]
