I can almost get you there, but I don't understand why
IE5.0beta2(5.00.0910.1309) isn't completing the job for me.  I'll still
work on it, but I thought I'd post these intermediate results in case
someone sees what I'm doing wrong.  The script below will display the
correct number of commas, but not the values!

My reference for using the "end()" function is from Microsoft's own
documentation ... I hadn't seen the function before and I only looked when
you posted your question.

Below this example I have an example conforming to
http://www.w3.org/TR/1998/WD-xsl-19980818 that seems to work just fine.

===============================8<==============================
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl";>

<xsl:template match="/">
  <xsl:apply-templates/>

  <BODY>
       valueList="
       <xsl:apply-templates select="Section"/>
       "
  </BODY>
</xsl:template> 

                 <!-- when more than one in list, punctuation after others -->
<xsl:template match="Section" >
   <xsl:apply-templates/>
   ,
</xsl:template> 

              <!-- no punctuation after last (same as if only one in list) -->
<xsl:template match="Section[end()]" >
   <xsl:apply-templates/>
</xsl:template> 

<xsl:template match="Foo">
  <xsl:apply-templates/>
</xsl:template>

<xsl:template match="Value">
  <xsl:apply-templates/>
</xsl:template>

</xsl:stylesheet>

Restricting oneself to http://www.w3.org/TR/1998/WD-xsl-19980818, the
following works just fine:
