There's an example in the current draft of doing exactly this. Basically
you replace this:

  <xsl:text>,</xsl:text>

with this:

  <xsl:if test=".[not-last-of-type()]">,</xsl:if>

That doesn't work with XT though and, looking at the draft I couldn't
see anything in the grammar that would allow it.

I'm also not sure it's sufficient in your case because you need to
look at the Section element not the Value element. This might do it
though:

  <xsl:if test="ancestor(Section)[not-last-of-type()]">,</xsl:if>

Except that you can't qualify an anchor so that isn't going to work
either... I suspect you'll need to loop on the Section elements and
then process Foo/Value like this:

  <xsl:for-each select="Section">
    <xsl:process select="Foo/Value"/>
    <xsl:if test=".[not-last-of-type()]">,</xsl:if>
  </xsl:for-each>

But that won't work if there is more than one Foo in a Section and
suffers from the same dubiousness as the example in the draft.

It's very horrible really. I've been fighting similar problems and
sometimes I can find a way round them and sometimes I can't.
