internal subset lost after using cloneNode

           Summary: internal subset lost after using cloneNode
           Product: Xerces-C++
           Version: 2.3.0
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: DOM
        AssignedTo: xerces-c-dev@xml.apache.org
        ReportedBy: kristone@hotmail.com


If you have document with an internal DTD (doctype) that contains an internal 
subset (e.g. notations, entities etc), then clone the whole document, using 
cloneNode and use DOMWriter to write the cloned document, there is no internal 
subset there.

Both enities and notation are still in the DTD though and can be reached via 
the DOMDocumentType::getEntities() and DOMDocumentType::getNotations() methods

It seems like the internal subset looses it's specified value !

original xml:
"<?xml version='1.0' encoding='iso-8859-1'?>
<!DOCTYPE pictures [<!NOTATION tiff SYSTEM 'image/tiff'> <!ENTITY PICTURE 
SYSTEM 'image.tif' NDATA tiff> <!ELEMENT pictures (#PCDATA)>]>
<pictures/>"

// code start

...
xercesc::DOMDocument * document = 
   parser->getDocument()->cloneNode( true );
...
writer->writeNode( &target, *document);
...

// code end

result xml:
"<?xml version='1.0' encoding='ISO-8859-1'?>
<!DOCTYPE pictures>
<pictures/>"
