RE: document() merge DISTINCT

In that case use
http://www.bayes.co.uk/xml/index.xml?/xml/utils/transquery/transquery.xm
l v2 with the -e option

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:tq="http://transquery.org"
>
<xsl:output method="xml" encoding="UTF-8" />
<xsl:param name="tq:input"/>
	<xsl:template match="/">
	    <xsl:for-each select="$tq:input//person[not(@id =
preceding::person/@id)]">
 		<xsl:sort select="@id" data-type="number"
order="ascending" />
 		<xsl:copy-of select="." />
 	    </xsl:for-each>
	</xsl:template>
</xsl:stylesheet>
