for a sample file:

<root>
	<x name="a">x:a</x>
	<x name="b">x:b1</x>

you can use test="count(//*[@name = ./@name]) = 1" :

---
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0" >
	<xsl:output method="xml" indent="yes"/>
	<xsl:template match="/">
		<xsl:copy>
			<xsl:apply-templates select="root"/>
		</xsl:copy>
	</xsl:template>
	<xsl:template match="x">
		<xsl:if test="count(//*[@name = ./@name]) = 1">
			<xsl:copy-of select="."/>
		</xsl:if>
	</xsl:template>
</xsl:stylesheet>

It's probably not very efficient - you'd need a Muenchian solution (I
suspect) for large documents.
