/**
 * IE 6 and 7 button[type=submit] shim
 *
 * @description Correct behaviour for button[type=submit] elements in IE 6 (all are submitted) and 7 (value is inner text). The 
 * following is only necessary if you must use button[type=submit] elements, otherwise stick to input[type=submit][class=button]
