Well, just because XLPage() was called with 'fr' is no guarantee that its the
language in use. Many recipes use the XLPage() function to load their
parameters into a fake 'language' by calling something like:
XLPage('foo-recipe',"$SiteGroup.FooRecipe);
So, there's really nothing you can do to look at the contents of $XL and
$XLLangs and tell the languages from the recipes.
Instead, you'll have to invent a new parameter like $SkinLang and use that. In
config.php, the user would set
$SkinLang='fr';
And in you skin.php you'd say something like:
global $SkinLang;
SDV($SkinLang,'en'); # default if not set by user.
$FmtPV['$SkinLang'] = '$GLOBALS["SkinLang"]';
Finally, you'd use $SkinLang in your template:
<html xmlns='http://www.w3.org/1999/xhtml' xml:lang='$SkinLang'
lang='$SkinLang'>
