When specifying the sort key on xsl:sort, it takes the nodes being selected 
as context for evaluating the select. So this should be:

<xsl:template match="Row">
  <xsl:apply-templates select="info">
    <xsl:sort select="date" order="descending"/>
  </xsl:apply-templates>
</xsl:template>

assuming <date> is a child of <info> (which your data shows it to be).

Notice also you don't need a test for whether there are any info elements; 
if there are none, none will be selected by your apply-templates.

I don't know why XMLSpy is working; Xalan is doing the right thing.

Cheers,
Wendell
