[Exist-open] [Q] Passing parameter from sitemap to XQuery

[<sju...@ko...>]

How can I pass a parameter I set in the sitemap to the xquery? More 
precisely, I need to extract the language/locale preferences coming 
with the request, and forward the language part of it to my xquery 
script.

I can't find any examples or docs illustrating this, and my imagination 
seems a little restricted right now.  I appreciate any help or 
suggestions.
