Ok, here is what I have:

This is the XML input:
<root>
   <foo @name=3D"1">a</foo>
   <foo @name=3D"1">b</foo>
   <foo @name=3D"1">a</foo>
   <foo @name=3D"2">c</foo>
   <foo @name=3D"2">c</foo>
   <foo @name=3D"2">d</foo>
</root>

And here is what I would have done with distinct-values:

<?xml version=3D"1.0" encoding=3D"utf-8"?>
<xsl:stylesheet xmlns:xsl=3D"http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl=3D"urn:schemas-microsoft-com:xslt" version=3D"1.0">

  <!-- root template: -->
  <xsl:template match=3D"/root">
    <xsl:call-template name=3D"fum">
      <xsl:with-param name=3D"in" select=3D"."/>
    </xsl:call-template>
  </xsl:template>

  <!-- sub-template: -->
  <xsl:template name=3D"fum">
    <xsl:param name=3D"in"/>
    <!-- this is the input -->
    <xsl:variable name=3D"fie" select=3D"$in/foo[@name=3D'1']" />
    <xsl:variable name=3D"fum" select=3D"distinct-values($fie)" />
  </xsl:template>

</xsl:stylesheet>

I expect to get only these nodes in fum:
   <foo @name=3D"1">a</foo>
   <foo @name=3D"1">b</foo>

(As a by-note, xsl:key can't be in the xsl:template......)

Thanks very much!
