+// DYNAMIC UPDATES

+// Dynamic updates reuses the DNS message format, but renames three of
+// the sections. Question is Zone, Answer is Prerequisite, Authority is
+// Update, only the Additional is not renamed. See RFC 2136 for the gory details.
+//
+// You can set a rather complex set of rules for the existence of absence of
+// certain resource records or names in a zone to specify if resource records
+// should be added or removed. The table from RFC 2136 supplemented with the Go
+// DNS function shows which functions exist to specify the prerequisites.
