the Muench method

I'd like to add my public plaudits to the insight of the Muench method 
for sorting and grouping, using keys. My stylesheet execution time has 
gone down to a 3rd, and is also more readable. The realisation that
I can cycle quickly over a widely dispersed set of nodes with

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

really makes me reassess my whole approach in several stylesheets.
