[Netconf] about subtree filtering

[WashamFan <Washam.Fan at huaweisymantec.com>]

Hi,

From sec6.4.6, rfc4741, there is a request using subtree:

   <rpc message-id="101"
          xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
       <get-config>
         <source>
           <running/>
         </source>
         <filter type="subtree">
           <top xmlns="http://example.com/schema/1.2/config";>
             <users>
               <user>
                 <name>fred</name>
                 <type/>
                 <full-name/>
               </user>
             </users>
           </top>
         </filter>
       </get-config>
     </rpc>

But what if users contains another element, let's say <role>
and I also want it returned, so is it legal, and is it returned as
the intent?

   <rpc message-id="101"
          xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
       <get-config>
         <source>
           <running/>
         </source>
         <filter type="subtree">
           <top xmlns="http://example.com/schema/1.2/config";>
             <users>
               <user>
                 <name>fred</name>
                 <type/>
                 <full-name/>
               </user>
               <role/>                            <!-- user's sibling-->
             </users>
           </top>
         </filter>
       </get-config>
     </rpc>

Thanks,
