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
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference

Abstract
This document is written to track implementations of the features of
the Session Descritpion Protocol (SDP).
Conventions used in this document
This document is not intended to be normative, and therefore makes no
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.

cases are in alphabetical order by record type (with general cases
coming first).
