This is a FAQ? the answer is that there is no way to modify a variable.

... you can do it like this.

<xsl:for-each select="stuff">
  <xsl:variable name="stuffcount" select="count()"/>
  <xsl:variable name="stuffpos" select="position() - 1"/>
   <xsl:for-each select="more">
    <xsl:variable name="morecount" select="count()"/>
    <xsl:variable name="morepos" select="position() - 1 + $stuffpos *
     <xsl:for-each select="again">
      <xsl:variable name="againpos" select="position() - 1 + $morepos *
      <xsl:text>Current position: </xsl:text>
      <xsl:value-of select="$againpos" />

... but this is, as you can see, very messy.
