Null pointer exception with XPath $foo[position() &gt; 1]

           Summary: Null pointer exception with XPath $foo[position() &gt;
                    1]
           Product: XalanJ2
           Version: CurrentCVS
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xalan.transformer
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


The attached file will cause a null pointer exception in the current Xalan CVS 
and many previous releases.  It can be eliminated by rewriting the XPath to 
avoid the [position() &gt; 1] clause if I remember correctly.
