----------------------------------------
Hi Janne,
Correct me if I am wrong, but this code should be executed any time a change
happens (e.g., renaming of headings or rearranging of paragraphs). Hence, even
if things change, the order of numbers should be the same. The way MediaWiki
handles it, it seems, is similar, though only appending a number when there are
duplicates (which sounds to me like keeping track of headings in some kind of
HashSet or something).
BTW, I initially tried to use a random number, but due to the fact that the
TableOfContents plugin does its own parsing, its set of numbers can be
different. Is there another mechanism you think would work better?

> When two or more headings in a given wiki article have the same title, their
> section IDs will be identical. The TableOfContents plugin will then not know
> which section ID to go to and will most likely go to the first one found.
