You use keys as well when sending notify to select which view processes the notify

What I'm trying to archive is that and update on zones in "internal" view does not contaminate zones in "external" view, or vice versa. I was wondering if using different key to limit update is a good practice, since I'm expecting "external" view on slave server will also receive notify upon update on "internal" zone at master, but just unable to query update due to incorrect key.
