number of pieces you supported, but that functionality was not useful in practice and consequently readers reported that they could produce any number of pieces in order to be useful. Thus, the behavior was change to allow readers simply to report whether
or not they support multiple pieces. Berk can probably provide more information.</span><o:p></o:p></p>
