Thats not how the lang attribute works. The lang attribute, tells web browsers, search engines, and other marchine, the language of element's content (including attribute's value for web browsers.) If you are exspecting the browser to (for example) translate the english phrase "The Clone" to french "El clone", then you are missing the point. The browser do not translate, it only try its best, to make it look like french (by manipulating it a little). For example, when you use double quotes around a word ("MAN"), the browser will try to make it look like french, by converting double quotes to e.g: guillemets («MAN»). It also helps screen readers, when pronouncing words.
