-  description
-    "This module defines an interface for managing alarms.  Main
-     inputs to the module design are the 3GPP Alarm Integration
-     Reference Point (IRP), ITU-T X.733, and ANSI/ISA-18.2 alarm
-     standards.
-     Main features of this module include:
-
-       * Alarm list:
-                 A list of all alarms.  Cleared alarms stay in
-                 the list until explicitly purged.
-
-       * Operator actions on alarms:
-                 Acknowledging and closing alarms.
-
-       * Administrative actions on alarms:
-                 Purging alarms from the list according to specific
-                 criteria.
-
-       * Alarm inventory:
-                 A management application can read all
-                 alarm types implemented by the system.
-
-       * Alarm shelving:
-                 Shelving (blocking) alarms according
-                 to specific criteria.
-
-       * Alarm profiles:
-                 A management system can attach further
-                 information to alarm types, for example,
-                 overriding system-default severity
-                 levels.
-
-     This module uses a stateful view on alarms.  An alarm is a state
-     for a specific resource (note that an alarm is not a
-     notification).  An alarm type is a possible alarm state for a
-     resource.  For example, the tuple:
-
-       ('link-alarm', 'GigabitEthernet0/25')
-
-     is an alarm of type 'link-alarm' on the resource
-     'GigabitEthernet0/25'.
-
-     Alarm types are identified using YANG identities and an optional
-     string-based qualifier.  The string-based qualifier allows for
-     dynamic extension of the statically defined alarm types.  Alarm
-     types identify a possible alarm state and not the individual
-     notifications.  For example, the traditional 'link-down' and
-     'link-up' notifications are two notifications referring to the
-     same alarm type 'link-alarm'.
-
-     With this design, there is no ambiguity about how alarm and
-     alarm clear correlation should be performed; notifications that
-     report the same resource and alarm type are considered updates
-     of the same alarm, e.g., clearing an active alarm or changing
-     the severity of an alarm.  The instrumentation can update the
-     severity and alarm text on an existing alarm.  The above alarm
-     example can therefore look like the following:
-
-       (('link-alarm', 'GigabitEthernet0/25'),
-        warning,
-        'interface down while interface admin state is up')
-
-     There is a clear separation between updates on the alarm from
-     the underlying resource, like clear, and updates from an
-     operator, like acknowledging or closing an alarm:
-
-       (('link-alarm', 'GigabitEthernet0/25'),
-        warning,
-        'interface down while interface admin state is up',
-        cleared,
-        closed)
-
-     Administrative actions like removing closed alarms older than a
-     given time is supported.
-
-     This YANG module does not define how the underlying
-     instrumentation detects and clears the specific alarms.  That
-     belongs to the Standards Development Organization (SDO) or
-     enterprise that owns that specific technology.
-
-     The key words 'MUST', 'MUST NOT', 'REQUIRED', 'SHALL', 'SHALL
-     NOT', 'SHOULD', 'SHOULD NOT', 'RECOMMENDED', 'NOT RECOMMENDED',
-     'MAY', and 'OPTIONAL' in this document are to be interpreted as
-     described in BCP 14 (RFC 2119) (RFC 8174) when, and only when,
-     they appear in all capitals, as shown here.

-
-       If the type is given as an XPath 1.0 expression, a resource
-       of type 'instance-identifier' matches if the instance is part
-       of the node set that is the result of evaluating the XPath 1.0
-       expression.  For example, the XPath 1.0 expression:

-       If the type is given as an object identifier, a resource of
-       type 'object-identifier' matches if the match object
-       identifier is a prefix of the resource's object identifier.
-       For example, the value:
-
-        1.3.6.1.2.1.2.2
-
-       would match the resource object identifier:
-

-
-       If the type is given as an UUID or a string, it is interpreted

-
-            If a leaf of this type is encoded in XML, all namespace
-            declarations in scope on the leaf element are added to
