Multiple key leafs for the same key cannot be requested inside the same instance of the list name
            node. Instead, each key value must be inside its own instance of the list name node; for
            example,
                <interface><interface-name>abc</interface-name></interface><interface>
                <interface-name>def</interface-name></interface>.
The following example shows a content match node on a list key.
     <?xml version="1.0" encoding="UTF-8"?>
     <rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
         <get-config>
             <source><running/></source>
             <filter>
                 <configure xmlns="urn:nokia.com:sros:ns:yang:sr:conf">
                     <router>
                         <interface>
                             <interface-name>Test</interface-name>
                         </interface>
                     </router>
                 </configure>
             </filter>
         </get-config>
     </rpc>
