xsl:for-each and variables

Can anyone tell me why the following will not work?

XML
<data>
<row>1</row>
<row>2</row>
<row>3</row>
<row>4</row>
</data>

XSL
<?xml version="1.0" standalone='no'?>
<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/XSL/Transform/1.0"
  xmlns="http://www.w3.org/TR/REC-html40"
  result-ns="">
 <xsl:variable name="temp">data/row</xsl:variable>
 <xsl:template match="/">
   <xsl:for-each select="data/row">
     value is <xsl:value-of select="."/>
   </xsl:for-each>
   <xsl:for-each select="$temp">
     value is <xsl:value-of select="."/>
   </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

If I take out the second for-each everything works.
When I leave it in, the output says "cannot convert to node-set".  Since the
value of temp is
the same as the static for-each (right?), shouldn't the result be the same?  Any
 work-arounds?

I'm trying to create a template that accepts the tags to process and thus need
the second format.

(using XT from August running on NT using the windows executable)

Any help is GREATLY appreciated.
