    Example migrated from Codex:

    As an example: HTML5 Boilerplate provides an X-UA-Compatible meta element by default. This element breaks validation, but can be moved to a header. Adding the following to functions.php fixes the validation issue and provides IE users a better experience.

    add_action( 'send_headers', 'add_header_xua' );
    function add_header_xua() {
    	header( 'X-UA-Compatible: IE=edge,chrome=1' );
