What's your use case? If you want to style a particular language then
there's the CSS :lang() pseudo-class.

Use cases are important because otherwise I think there are very few
pages with multiple lang attributes...

That's true. However, if the case isn't important, we can do tree
traversal (modulo HTTP Content-Language header and pragma) or exhaust
element.matchesSelector(":lang(xxx)").

Indeed.
