The ISO/IEC CD 14496-22 3rd edition suggests using the ssty feature to provide glyph variants more suitable for use in scripts (for example primes used as superscripts). Starting with Firefox 29, this is done automatically by the MathML rendering engine. The ISO/IEC CD 14496-22 3rd edition also suggests applying the dtls feature to letters when placing mathematical accents to get dotless forms (for example dotless i, j with a hat). Starting with Firefox 35, this is done automatically by the MathML rendering engine. You can override the default values determined by the MathML rendering engine with CSS.
