               The <code>protocol</code> attribute specifies the protocol to
               access to the requested image. Possible values are "nbd",
-              "iscsi", "rbd", "sheepdog", "gluster" or "vxhs".  If the
-              <code>protocol</code> attribute is "rbd", "sheepdog", "gluster"
-              or "vxhs", an additional attribute <code>name</code> is
-              mandatory to specify which volume/image will be used. For "nbd",
-              the <code>name</code> attribute is optional. For "iscsi"
-              (<span class="since">since 1.0.4</span>), the <code>name</code>
-              attribute may include a logical unit number, separated from the
-              target's name by a slash (e.g.,
+              "iscsi", "rbd", "sheepdog", "gluster" or "vxhs".
