How to Include Topic Sections in TOC
To include topic sections in the table of contents, set the
args.css.param.numbering-sections
transformation parameter to yes. In this case,
they are numbered according the numbering scheme set by
the args.css.param.numbering
parameter.
If you want to prevent topic sections from being numbered in your output,
set the value of the args.css.param.numbering-sections
parameter to
no.
