    The same way you add attributes to any other tag in Haml:

    %html{:xmlns => "http://www.w3.org/1999/xhtml", "xml:lang" => "en", :lang => "en"}
    

    Haml actually has a built in helper method for these attributes, so you can just do:

    %html{html_attrs}
    

    which defaults to ‘en-US’ as the language, or pass the language string you want to use:

    %html{html_attrs('en')}
