Hmh, I think you missed my point about having a conditional
construct in XPath.

<xsl:function name="my:max">
  <xsl:param name="nl"/>
  <xsl:variable name="first" select="nl [1]"/>
  <xsl:variable name="max-of-rest"
     select="if (nl [2], my:max (nl [position () > 1]), /..)"/>
  <xsl:result select="if ($max-of-rest,
                          if ($first > $max-of-rest, $first, $max-of-rest),
                          $first)"/>
</xsl:function>
