/*
 * 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
