I use this configuration to follow with the HTML5boilerplate.
config{
doctype = html_5
doctype(
<!doctype html>
<!--[if lt IE 7 ]> <html lang="de" class="no-js ie6"> <![endif]-->
<!--[if IE 7 ]> <html lang="de" class="no-js ie7"> <![endif]-->
<!--[if IE 8 ]> <html lang="de" class="no-js ie8"> <![endif]-->
<!--[if IE 9 ]> <html lang="de" class="no-js ie9"> <![endif]-->
<!--[if (gt IE 9)|!(IE)]><!-->
)
htmlTag_setParams = lang="de" class="no-js no-ie"><!--<![endif]--
}
The problem is that when I have a site with several alternative languages, the langattribute doesnt update.
Does anyone have an idea how to solve this?
