\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).

All the mechanisms specified in this document are described in both
prose and an augmented Backus-Naur form (BNF) similar to that used in
RFC 2068 [H2.1].  It is described in detail in
\cite{Croc9610:Augmented}.

In this draft, we use indented and smaller-type paragraphs to provide
background and motivation.  Some of these paragraphs are marked with HS,
AR and RL, designating opinions and comments by the individual authors
which may not be shared by the co-authors and require resolution.
