XSLT top-level variables don't get re-initalized between transformations

           Summary: XSLT top-level variables don't get re-initalized between
                    transformations
           Product: Ant
           Version: 1.5.3
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Core tasks
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


build.xml:
<project default="test">
  <target name="test">
    <xslt basedir="." destdir="out" includes="in*.xml" style="test.xsl"/>
  </target>
</project>

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

  <xsl:variable name="var" select="string(/test/value)"/>

  <xsl:template match="/">
    The test value is: <xsl:value-of select="$var"/>
  </xsl:template>

</xsl:stylesheet>

in1.xml:
<test>
  <value>from in1.xml</value>
</test>

in2.xml:
<test>
  <value>from in2.xml</value>
</test>

The (incorrect) output:
out/in1.html:
    The test value is: from in1.xml

out/in2.html:
    The test value is: from in1.xml


in2.html should say "from in2.xml". If I remove the variable and just use 
the "/test/value" expression inline, then the correct value is output.

Worse yet, when I keep the top-level variable and remove the string() function 
surrounding "/test/value", I get a NullPointerException when the second file 
is processed.
