    <Paragraph position="0"> Rounds and Manaster-Ramer \[9\] suggested encoding multiple strata in terms of a &amp;quot;level&amp;quot; attribute, using path equations to state correspondences across strata. Unfortunately, &amp;quot;unchanged' relations in a stratum must be explicitly &amp;quot;carried over&amp;quot; via path equations to the next stratum. Even worse, these &amp;quot;carry over&amp;quot; equations vary from case to case. SFG avoids this problem.</Paragraph>
