'preceding-sibling' axis not updating correctly during template processing

           Summary: 'preceding-sibling' axis not updating correctly during
                    template processing
           Product: XalanJ2
           Version: 2.3
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Xalan-CmdLine
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: steve.heil@fishersci.com


'preceding-sibling' values (including child element values & attribute values) 
are not being updated after the second sibling node during processing of a set 
of multiple sibling nodes.

e.g. during processing of 4 sibling nodes, for 1st node, 'preceding-sibling' 
values are null (as expected), for 2nd node, 'preceding-sibling' values are 
values from 1st sibling node (as expected), for 3rd and subsequent 
nodes, 'preceding-sibling' values are always values from 1st sibling node.
