Re:  Creating a hierarchical table of contents using  x
I think you may be working too hard, and that the following will do
what you want:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  version="2.0">
  
  <xsl:output indent="yes" method="xml"/>
  
  <xsl:template match="/">
    <wrap>
      <xsl:apply-templates select="//level1 | //level2 | //level3"/>
    </wrap>
  </xsl:template>

  <xsl:template match="level1|level2|level3">
    <xsl:number level="multiple" count="level1|level2|level3" format="1.1. "/>
    <xsl:value-of select="@title"/><br/><xsl:text>&#x0A;</xsl:text>
  </xsl:template>

</xsl:stylesheet>


It is worth reading the discussion of <xsl:number> in a worthwhile
reference (I use Kay's) a few times, and playing around with it.
