That's a sensible suggestion at first sight. It might require some thinking
about implementation. Currently I say:

 <xsl:for-each select="key('CLASSMEMBERS',$foo)">

(you can imagine what the key is, and what $foo is).

would adding

   <xsl:sort select="@z-index"/>
   <xsl:sort select="position()"/>
 
do the job? does position() do the right thing here?
