+    description
+      "This extension allows for defining metadata annotations in
+       YANG modules.  The 'md:annotation' statement can appear only
+       at the top level of a YANG module or submodule, i.e., it
+       becomes a new alternative in the ABNF production rule for
+       'body-stmts' (Section 14 in RFC 7950).
+
+       The argument of the 'md:annotation' statement defines the name
+       of the annotation.  Syntactically, it is a YANG identifier as
+       defined in Section 6.2 of RFC 7950.
+
+       An annotation defined with this 'extension' statement inherits
+       the namespace and other context from the YANG module in which
+       it is defined.
+
+       The data type of the annotation value is specified in the same
+       way as for a leaf data node using the 'type' statement.
+
+       The semantics of the annotation and other documentation can be
+       specified using the following standard YANG substatements (all
+       are optional): 'description', 'if-feature', 'reference',
+       'status', and 'units'.
+
+       A server announces support for a particular annotation by
+       including the module in which the annotation is defined among
+       the advertised YANG modules, e.g., in a NETCONF <hello>
+       message or in the YANG library (RFC 7950).  The annotation can
+       then be attached to any instance of a data node defined in any
+       YANG module that is advertised by the server.
+
+       XML encoding and JSON encoding of annotations are defined in
+       RFC 7952.";
