   Status of this Memo
   
      This document is an Internet-Draft and is in full conformance with
      all provisions of Section 10 of RFC2026.
   
      Internet-Drafts are working documents of the Internet Engineering
      Task Force (IETF), its areas, and its working groups.  Note that
      other groups may also distribute working documents as Internet-
      Drafts.
   
      Internet-Drafts are draft documents valid for a maximum of six months

   Abstract
   
      This document is written to track implementations of the features of
      the Session Descritpion Protocol (SDP).

      reference to RFC 2119 conventions.
   
   
   1  Introduction
   
      The table which follows uses this definition of interoperability:
      transfer of a correctly composed and formatted session description
      from a sender to a receiver, where the latter demonstrates
      understanding of the description at the syntactic and semantic level.
