As others have pointed out, it's a bug in Xalan. Here's a possible
work-around:

<!-- collect all the unique person/date elements into a variable -->
<xsl:variable name="dates"
              select="person/date
                       [generate-id(.)=
                        generate-id(key('myKey',
                                        concat( account, '::', .))[1])]" />

<!-- iterate over the months -->
<xsl:for-each select="$months">

  <!-- sorting them according to descending @value
       (could use position() instead) -->
  <xsl:sort select="@value" data-type="number" order="descending" />

  <!-- iterate over each of the dates in $dates whose @name
       starts with the current month -->
  <xsl:for-each select="$dates[starts-with(., current()/@name)]">
     ...
  </xsl:for-each>

</xsl:for-each>

I hope that helps,

Jeni
