+\section{Reading a file}
+
+Tokenization.
+
+Treatment of spaces, such as the trap that \verb|\~~a| is equivalent to
+\verb|\~a| in expl syntax, or that \verb|~| fails to give a space at the
+beginning of a line.
+
+\section{Structure of tokens}
+
+Copy there the section ``Description of all possible tokens'' from \texttt{l3token}.
+
+\section{Quantities and expressions}
+
+Integer denotations, dimensions, glue (including \texttt{fill} and \texttt{true pt} and the like).
+
+Syntax of integer expressions (including the trap that \verb|-(1+2)| is invalid).
+
+\section{\LaTeX3 terms}
+
+Terms like ``intexpr'' or ``seq var'' used in syntax blocks.
