And please remove the # from the current id of the header. It is more
confusing, than helping (Linking works, but javascript selection is
complicated)

db is referring to this:

<h2><span class="mw-headline" id="#Basic_information">Basic information</span></h2>

The "#" in the CSS id attribute is wrong.

I'm not sure if the ID should be canonical (similar to file description pages) or if it should use the value of the h2. I guess having both would be best, if possible?

It is possible to get ids for the header and table, which are not changed
across languages?

I agree, they shouldn't be dependent on localisation (both English and non-English). If "Basic information" is ever changed to "General data" or whatever, the anchors should stay as-is, just like we have #mw-portal, #toc, footer, #file etc.

The leading # is fixed (bug 44989).
