RE:  Counting nodes efficiently
<xsl:template match="*" priority="0.2">

Stops saxon warning me about ambiguity,
and produces (I think) the same output.
Jeni had a minor addition which also added a document identity
to ensure X document resolution.

 <para _id="para_2_5">.... </para>
then becomes

 <para  _id="doc1_para_2_5"></para>
 or whatever.

  Not too hard to do with a stylesheet parameter,
and easily added to Dimitres ideas.

Nice one Dimitre.
  regards DaveP

    So, the correct override for elements is:
    
      <xsl:template match="*">
        <xsl:param name="pnAncestors" select="0"/>
        <xsl:param name="pnPreceding" select="0"/>
        
        <xsl:copy>
          <xsl:copy-of select="@*"/>
          <xsl:attribute name="_id">
            <xsl:value-of select=
                        "concat(name(), '_',
                                $pnAncestors, '_', 
                                $pnPreceding 
                                )"/>
          </xsl:attribute>
          <xsl:apply-templates select="node()[1]">
            <xsl:with-param name="pnAncestors" 
                            select="$pnAncestors+1"/>
            <xsl:with-param name="pnPreceding"
                            select="$pnPreceding"/>
          </xsl:apply-templates>
        </xsl:copy>
        <xsl:apply-templates select="following-sibling::node()[1]">
          <xsl:with-param name="pnAncestors" 
                          select="$pnAncestors"/>
          <xsl:with-param name="pnPreceding"
                          select="$pnPreceding+1"/>
              
        </xsl:apply-templates>
        
      </xsl:template>
