The formatting commands used in this template are:
-\dt \i\c{%N}
+\dt \I{%N-upper}\c{%N}
\dd Expands to the visible title of the section, with white space
removed. So in a chapter declared as \q{\cw{\\C\{fish\} Catching
this to \q{\cw{:\_}}, then the chapter title might look something
like \q{Chapter 2: Doing Things}.
-\dt \I{\cw{\\cfg\{xhtml-section-numeric\}}}\cw{\\cfg\{xhtml-section-numeric\}\{}\e{boolean}\cw{\}}
+\dt \I{\cw{\\cfg\{xhtml-section-numeric\}}}\cw{\\cfg\{xhtml-section-numeric\}\{}\e{level}\cw{\}\{}\e{boolean}\cw{\}}
\dd Specifies whether section headings at a particular level should
contain the word \q{Section} or equivalent (if \c{false}), or should
first-level headings (\c{\\H}), 1 means second-level headings
(\c{\\S}), 2 means the level below that (\c{\\S2}), and so on.
-\dt \I{\cw{\\cfg\{xhtml-section-suffix\}}}\cw{\\cfg\{xhtml-section-suffix\}\{}\e{text}\cw{\}}
+\dt \I{\cw{\\cfg\{xhtml-section-suffix\}}}\cw{\\cfg\{xhtml-section-suffix\}\{}\e{level}\cw{\}\{}\e{text}\cw{\}}
