Maybe this helps: My *original* intention for the
numbering was
not only making the article more structured (in a way), but
enabeling:
1. A short table of contents generated automatically from the
headings, to be displayed at the beginning of the article, with
links directly to the matching piece of text (and "UP" links there)
2. Based on this (the headings then would be marked with <a
name="1.2.3">), linking to [[topix#subtopic]].
But, then I didn't know wether to link to the heading itself (a
lot of typing, and the heading could change), or to the heading
*number* (like [[topic#1.1]]), which can change as well.
That's another thing to think about. BTW, I implemented page
fragment links (e.g., [[Chemistry#history]], which links to
[[##history]] on the Chemistry page), though I haven't made much
noise about it because I'm still not sure they're needed--for one
thing, they encourage long pages, and I don't like my syntax. But
headings do seem like a natural match there.
