For all following numeric components Algorithm 3 is called. For the next component, the condition in line 1 is true, so it will remove trailing zeros (i.e., both "020" and "02" will become "02") and then it will use stringwise comparison. That is, versions 1.020.3 and 1.02.3 will be considered equal. Ulrich
