+ * Reference RFC 6020.
+ *
+ * YANG allows the definition of notifications suitable for NETCONF.
+ * YANG data definition statements are used to model the content of the
+ * notification.
+ *
+ * The "notification" statement is used to define a NETCONF
+ * notification.  It takes one argument, which is an identifier,
+ * followed by a block of substatements that holds detailed notification
+ * information.  The "notification" statement defines a notification
+ * node in the schema tree.
+ *
+ * If a leaf in the notification tree has a "mandatory" statement with
+ * the value "true", the leaf MUST be present in a NETCONF notification.
+ *
+ * If a leaf in the notification tree has a default value, the NETCONF
+ * client MUST use this value in the same cases as described in
+ * Section 7.6.1.  In these cases, the client MUST operationally behave
+ * as if the leaf was present in the NETCONF notification with the
+ * default value as its value.
+ *
+ * If a "config" statement is present for any node in the notification
+ * tree, the "config" statement is ignored.
+ *
+ * The notification's substatements
