+  description
+    "This module contains a collection of YANG definitions for
+     fabric state, representing topology that either is learned
+     or results from applying topology that has been
+     configured per the ietf-dc-fabric-topology model, mirroring
+     the corresponding data nodes in this model.
+
+     This model mirrors the configuration tree of ietf-dc-fabric
+     -topology but contains only read-only state data.  The model
+     is not needed when the implementation infrastructure supports
+     the Network Management Datastore Architecture (NMDA).
