\section{Notational Conventions}

Since many of the definitions and syntax are identical to HTTP/1.1, this
specification only points to the section where they are defined rather
than copying it. For brevity, [HX.Y] is to be taken to refer to Section
X.Y of the current HTTP/1.1 specification (RFC 2068 \cite{rfc2068}).

All the mechanisms specified in this document are described in both
prose and an augmented Backus-Naur form (BNF) similar to that used in
[H2.1].  It is described in detail in RFC 2234 \cite{rfc2234}, with the
difference that this RTSP specification maintains the ``1\#'' notation
for comma-separated lists. 

In this draft, we use indented and smaller-type paragraphs to provide
background and motivation.  This is intended to give readers who were not
involved with the formulation of the specification an understanding of why
things are the way that they are in RTSP.
