sort data-type="text" not sorting text with "-" correctly

           Summary: sort data-type="text" not sorting text with "-"
                    correctly
           Product: XalanJ2
           Version: CurrentCVS
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Xalan
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: tom.amiro@sun.com


When doing text sorts, both Xalan and XSLTC appear to be ignoring the 
"-" character. Textually, the - should come before 0.
Here's a simple test case modified from sort40.

xsl file
========
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

<xsl:template match="/">
  <xsl:variable name="numnodes" select="doc/num" />
  <out>
    Descending order....
    <xsl:for-each select="$numnodes">
      <xsl:sort data-type="text" />
      <xsl:value-of select="."/><xsl:text> </xsl:text>
    </xsl:for-each>
  </out>
</xsl:template>

</xsl:stylesheet>


xml file
