If the values are present in the source XML file, then to accumulate 
the values in a data structure one can use node-set union operation.

One can later iterate (for-each) through the node-set or pass and increment
position in the node-set as a parameter for the template.

For example, the simple stylesheet below uses node-set 
to implement a grouping algorithm.

<xsl:transform 
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	version="1.0">

  <xsl:template name="group-n">

    <xsl:param name="e" select="."/>
    <xsl:param name="es" select="."/>
    <xsl:param name="i">1</xsl:param>
    <xsl:param name="n"/>
    <xsl:param name="group">group</xsl:param>

    <xsl:variable name="enext" select="$e/following-sibling::*[1]"/>

    <xsl:choose>
      <xsl:when test="$i = $n">
	<xsl:element name="{$group}">
	  <xsl:apply-templates select="$e|$es"/>
	</xsl:element>
	<xsl:for-each select="$enext">
	  <xsl:call-template name="group-n">
	    <xsl:with-param name="group" select="$group"/>
	    <xsl:with-param name="n" select="$n"/>
	  </xsl:call-template>
	</xsl:for-each>
      </xsl:when>
      <xsl:otherwise>
	<xsl:call-template name="group-n">
	  <xsl:with-param name="group" select="$group"/>
	  <xsl:with-param name="i" select="$i+1"/>
	  <xsl:with-param name="n" select="$n"/>
	  <xsl:with-param name="e" select="$enext"/>
	  <xsl:with-param name="es" select="$es|$enext"/>
	</xsl:call-template>
      </xsl:otherwise>
    </xsl:choose>

  </xsl:template>

</xsl:transform>
