I have an XML document that consists of <row> elements:

<x>3</x>
<y>4</y>
</row>
<row>
<x>1</x>
<y>2</y>
</row>

I want to eliminate duplicate rows.
The following XSLT stylesheet, also seems to work,
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:fn1="http://fn1";
exclude-result-prefixes="xs fn1" version="2.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="Document">
<Document>
<xsl:apply-templates
select="row[not(fn1:hasRowOccuredEarlier(.))]"/>
</Document>
</xsl:template>
<xsl:template match="row">
<xsl:copy-of select="."/>
</xsl:template>
<xsl:function name="fn1:hasRowOccuredEarlier" as="xs:boolean">
<xsl:param name="row" as="element(row)"/>
<xsl:sequence select="some $r in $row/preceding-sibling::row
satisfies deep-equal($r/*, $row/*)"/>
</xsl:function>
</xsl:stylesheet>
