			<description><![CDATA[There is indeed change of defence motive. I am not sure what exactly is meant by 'cumulative' or 'progressive' black correction. I assumed these terms to mean the more commonly known 'tertiary' and 'quaternery' black corrections. See the interesting discussion here where the concept of carry over of black errors is explained. http://www.matplus.net/start.php?px=1386189353&app=forum&act=posts&fid=xshow3&tid=647]]></description>
