1.  Introduction

   This draft defines one new RTCP SDES item and one new XR Report Block
   to carry parameters which identify a measurement for use in a range
   of RTP applications.  The XR Report Block and the SDES item do not
   contain any measurement results (metrics).  However, the XR Report
   Block provides information relevant to a measurement reported in one
