Let's try to remember that many of the comments/ requests for alternate publication formats have been to make "display" more a function of the devices being used. Depending on type style variations (style, size, font variations, underlining, etc.) would pretty much defeat that particular claimed requirement. As I take Sam's note to sort of point out, even the use of uppercase to imply specific semantics can be problematic; we should at least strive to not make things worse, IMO. john
