+  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.

+
+       assuming that the interface 'eth1' is of type
+       'ianaift:ethernetCsmacd'.
+
+       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
+       as an XML Schema regular expression, which matches a resource
+       of type 'yang:uuid' or 'string' if the given regular
+       expression matches the resource string.
+
+       If the type is given as an XPath expression, it is evaluated
+       in the following XPath context:
+
+         o  The set of namespace declarations is the set of prefix
+            and namespace pairs for all YANG modules implemented by
+            the server, where the prefix is the YANG module name and
+            the namespace is as defined by the 'namespace' statement
+            in the YANG module.
+
+            If a leaf of this type is encoded in XML, all namespace
+            declarations in scope on the leaf element are added to
+            the set of namespace declarations.  If a prefix found in
+            the XML is already present in the set of namespace
+            declarations, the namespace in the XML is used.
+
+         o  The set of variable bindings is empty.
+
+         o  The function library is the core function library, and
+            the functions are defined in Section 10 of RFC 7950.
+
+         o  The context node is the root node in the data tree.";
