Wrap the xsl:for-each that iterates over the layer_params elements in
an xsl:variable:

  <xsl:variable name="positionList">
    <xsl:for-each select="//layer_params">
      ...
    </xsl:for-each>
  </xsl:variable>

then take the substring of that variable's value:

  substring($positionList, 1, string-length($positionList) - 1)

Cheers,

Jeni
