Re: problem passing parameter to apply-templates

  <xsl:apply-templates
  select="document('../xml/clasif2.xml')/clasif2">

so you are applying templates to clasif2 nodes.

You don't show any template matching clasif2 If you hav enot defined one
the default template equivalent to

<xsl:template match="clasif2">
  <xsl:apply-templates/
</xsl:template>

will be applied and that does not pass on the parameter you need

<xsl:template match="clasif2">
  <xsl:param name="nodes"/>
  <xsl:apply-templates>
    <xsl:with-param name="nodes" select="$nodes"/>
 </xsl:apply-templates>
</xsl:template>

or possibly with * instead of clasif2 above as you need to pass this all
the way down to your item element.
