Passing parameters to templates with xsl:apply-templates does not work

<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type="text/xsl" href="transform.xsl"?>
<document>
  <items>
    <item/>
  </items>
  <start value="Works"/>
</document>

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method='html' version='5.0' encoding='UTF-8' indent='yes'/>
    <xsl:template match="/document/start">
        <xsl:apply-templates select="/document/items/*">
            <xsl:with-param name="par" select="@value"/>
        </xsl:apply-templates>
    </xsl:template>
    <xsl:template match="item">
        <xsl:param name="par"/>
        <xsl:value-of select="$par"/>
    </xsl:template>
</xsl:stylesheet>
