 ] The number of optional arguments that can be used with this layout.
  This is useful for things like section headings, and only makes sense with
  LaTeX.
+ Note that, on output, the optional arguments will all precede any required
+ arguments (see below).
+ So one can have constructs like:
 \end_layout
 
+\begin_deeper
+\begin_layout LyX-Code
+
+\backslash
+mycmd[opt1]{req1}{contents of paragraph}
+\end_layout
+
+\begin_layout Standard
+but one cannot have things like: 
+\end_layout
+
+\begin_layout LyX-Code
+
+\backslash
+mycmd[opt1]{req1}[opt2]{contents of paragraph}
+\end_layout
+
+\begin_layout Standard
+at least, not without ERT (with which you can have anything).
