Barracuda: About URLRewriting using DefaultDOMWriter

Hi, Barracuda Community 
I met a  Problem ----    on Barracuda ( 1.1.1 )  URLRewritting  and XMLC 2.1
 
                   We are using  org.enhydra.barracuda.core.util.dom.DefaultDOMWriter.  
                                --  write(Node node, HttpServletResponse resp, OutputOptions oo)  
                      and in the OutputOptions we add the implemented  URLRewriter . 
 
Result   ---   if we turned off the Brower cookie , the rendered page still don't have the Rewriting. 
 
Found  ----  and Looked at the source code,  actually it is  org.enhydra.barracuda.core.util.dom.io. BaseDOMFormatter 
 
                     try to do the real job , and the way it did is before using any Rewriter Passed , checking whether the Document or Node being rendered 
 
                     implemented  from Interface org.enhydra.barracuda.core.util.dom.io.DocumentInfo.  
 
Surprise ---   ( !!!!! This  DocumentInfo   is not implemented by any class in Barracuda or XMLC  --- XMLCObject   !!!!)
 
                       and All the XMLCObject did implement   ---- org.enhydra.xml.io.DocumentInfo
 
 Change ----  And we tested change the BaseDOMFormatter to use the DocumentInfo in XMLC  and URL Rewriting works perfectly  !!!
 
So , I guess may be we have some reason to have two DocumentInfo , or may be a bug.
