[xsl] sort parameter problem

[Guillaume Rousse <rousse@xxxxxxxxxxxxxx>]

The following construct hasn't any sort effect when called with sort=bar 
parameter:
<xsl:template name="list-foos">
  <xsl:param name="sort"/>
  <xsl:for-each select="foos/foo">
    <xsl:sort select="$sort"/>
    [..]
  </xsl:for-each>
</xsl:template>

However, hardcoding sort value is OK:
<xsl:template name="list-foos">
  <xsl:param name="sort"/>
  <xsl:for-each select="foos/foo">
    <xsl:sort select="bar"/>
    [..]
  </xsl:for-each>
</xsl:template>

The XSL spec says:
xsl:sort has a select attribute whose value is an expression.

So, am i doing something wrong there, or should i report a bug in xalan-j 
2.2.D10 ?
