I'm confused.
Here Google recommends not to use parameters for different languages [googlewebmastercentral.blogspot.de...]
And jet they use them all over the place [support.google.com...]

Here they say: "Keep in mind that Google ignores all code-level language information, from “lang” attributes..." [googlewebmastercentral.blogspot.de...]
And here they recommend lang attributes: [support.google.com...]

Can someone bring light in the darkness?
