4.1.8 Confirm Response Message

If the Confirm message is verified without error, the device returns a ConfirmResponse SOAP response message to the control point. The following example demonstrates a ConfirmResponse message where the <DeviceConfirmNonce> element is encoded in a MIME base64 scheme:

 <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"
     s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
   <s:Body>
     <u:ConfirmResponse xmlns:u="urn:schemas-microsoft-com:service:mstrustagreement:1">
       <DeviceConfirmNonce>
         rD5m4Fgi+ifV9GS+611aO3T998Q=
       </DeviceConfirmNonce>
     </u:ConfirmResponse>
   </s:Body>
 </s:Envelope>

After the control point verifies the response message, and if there is no error, DTAG is completed and a trust relationship is established between the control point and the device.
