+// Package networkattrs gives access to the provider Neutron plugin, allowing
+// network extended attributes. The provider extended attributes for networks
+// enable administrative users to specify how network objects map to the
+// underlying networking infrastructure. These extended attributes also appear
+// when administrative users query networks.
+//
+// For more information about extended attributes, see the NetworkExtAttrs
+// struct. The actual semantics of these attributes depend on the technology
+// back end of the particular plug-in. See the plug-in documentation and the
+// OpenStack Cloud Administrator Guide to understand which values should be
+// specific for each of these attributes when OpenStack Networking is deployed
+// with a particular plug-in. The examples shown in this chapter refer to the
+// Open vSwitch plug-in.
+//
+// The default policy settings enable only users with administrative rights to
+// specify these parameters in requests and to see their values in responses. By
+// default, the provider network extension attributes are completely hidden from
+// regular tenants. As a rule of thumb, if these attributes are not visible in a
+// GET /networks/<network-id> operation, this implies the user submitting the
+// request is not authorized to view or manipulate provider network attributes.
