preceding sibling test

Hi,

   I'm trying to upgrade an old XSL file to the latest XSLT standard and
have a small problem when testing against a previous sibling

My XML file contains a number of ITEM's which contain amongst other things a
<USER> and while processing each <ITEM> I need to check if the <USER> has
changed.

	I used to use the following...

	<xsl:template match="ITEM">
	   <xsl:if test="not(USER = from-preceding(USER))">
	      <xsl:apply-templates select="USER"/>
	   </xsl:if>
	... etc

	With the new format I thought this should read

	<xsl:template match="PB_ITEM">
	   <xsl:if test="not(USER = preceding-sibling::USER[position()=1])">
	      <xsl:apply-templates select="USER"/>
	   </xsl:if>
	... etc

	but this always evaluates to true, so what am I doing wrong ?
