RE: [xsl] problem with variable and position()

This template could as well be simply

  <xsl:template match="text()" mode="description">
    <xsl:variable name="descPos" select="position()"/>
    <xsl:apply-templates select="text()[position()>$descPos]"/>
  </xsl:template>

unless you have multiple different templates that match text nodes in "description" mode.

> <xsl:template match="text()[position()>$descPos]">
>                               <xsl:value-of select="."/>
> </xsl:template>  

And this should be

  <xsl:template match="text()">
    <xsl:value-of select="."/>
  </xsl:template>

or, you don't even need this, because the build-in template rule will take care of it

For one, the descPos variable will be out of scope in the other template -- see the XSLT spec for variable scope. Also, variable references are not allowed in match patterns.
