Suppose I'm writing a
report document, where most chapters have sections, with subsections within them; but some chapters (say, an introduction) is shorter than the others - about the same size as a section of a "normal" chapter; and I only want this short-chapter to have subsection-level headings.
If I do this, it either messes up the numbering (e.g. I get 1.0.1, 1.0.2 for these section/subsections) - or I also drop the numbering, in which case these subsections are removed from the table-of-contents and I have to reintroduce them "manually".
Anyway, I was wondering what's the idiomatic way to deal with this scenario, or at least what you have found useful to go about it.
