* `version` the version to return, defaults to CoreDNS.
* `authors` what authors to return. No default.
-Note this middleware can only be specified for a zone once. This is because it hijacks
-the zones `version.bind`, `version.server`, `authors.bind`, `hostname.bind` and
-`id.server`, which means it can only be routed to one middleware.
+Note that you have to make sure that this middleware will get actual queries for the
