This book uses one terminological convention that merits special note. There are many BIND configuration substatements that you can use within several different statements. For example, you can specify allow-transfer within a zone statement, within an options statement, and within a view statement. When I'm referring only to the first use, I call it the allow-transfer zone substatement. When referring to any of the three, I just call it the allow-transfer substatement. While I'm not sure this convention is common, it seemed like a natural, compact way of expressing the idea.
