Nice one, but in my case this sitemap is actually called from another
pipeline, that provides the actual lang request-parameter. I have a =
separate
piece logic to work out the right locale (not only based on the users
locale).

currently stands?

Of course!
I rely on your and the Cocoon community's work all day long, so it's =
just
decent to give something back.

The filename pattern is <filename>_<lang>.<ext>, and the idea is to take =
the
file with the longest <lang>-string that matches the complete or partial
language.
If no match is found, just produce the last one (wich is also the =
default
language, usually english or norwegian (!) for norwegian only sites.

Thanks, but you haven't seen the stylesheet yet ;)
That's the weak link, since it's not able to compute the 100% correct
language.
But it's still good enough for me, event if it doesn't work for all =
cases.=20
