Re: [xsl] copy without duplicates

yes but inconvient to use keys so might be quite a bit slower than a key
based grouping mechanism.

However if you have a node-set extension (almost every system except
mozilla has one) then you can  do your two-pass version within the same
stylesheet as usual with node-set.

<xsl:template match="/"
<xsl:variable name="x">
  <xsl:apply-templates mode="a"/>
</xsl:variable>
so $x now has what would have been teh output of your first stylesheet
then do
<xsl:apply-template mode="b" select="exslt:node-set($x)"/>
where mode b does whatever your 2nd stylesheet was going to do
</xsl:template
