I don't get this error when using Xalan-J 2.4.1 (I don't
have 2.4.0 to test).  

I can't see why the line in question should produce an
error since the referrer parameter is declared:

<xsl:template match="*" mode="object.xref.template">
  <xsl:param name="purpose"/>
  <xsl:param name="xrefstyle"/>
  <xsl:param name="referrer"/>

  <xsl:call-template name="gentext.template">
    <xsl:with-param name="context" select="'xref'"/>
    <xsl:with-param name="name">
      <xsl:call-template name="xpath.location"/>
    </xsl:with-param>
    <xsl:with-param name="purpose" select="$purpose"/>
    <xsl:with-param name="xrefstyle" select="$xrefstyle"/>
    <xsl:with-param name="referrer" select="$referrer"/> <!-- Line 130 -->
  </xsl:call-template>
</xsl:template>

Do you get this same error with the 1.57.0 stylesheets,
which had a very similar template?
