\section{Changes Made in Version 01}
\begin{itemize}
% hgs 07/23/00
\item Uniform syntax specification for semicolon parameters:
\begin{syntax}
Foo        & = & "Foo" ":" something *( ";" foo-param )\\
foo-param  & = & "bar" "=" token\\
           &$|$& generic-param
\end{syntax}

% hgs 08/06/00
\item Removed \header{np-queried} \header{user} parameter since this is
now part of a tel URL extension parameter.

% hgs 08/06/00
\item In SDP section, noted that if the capabilities
intersection is empty, a dummy format list still has to be returned due
to SDP syntax constraints.  Previously, the text had required that no
formats be listed.  (Brian Rosen)

% hgs 07/23/00
\item Reorganized tables~\ref{tab:headers1} and \ref{tab:headers2} to
show proxy interaction with headers rather than ``end-to-end'' or
``hop-by-hop''.


\end{itemize}
