Chained call to external entities is not conform to W3C XML specification

           Summary: Chained call to external entities is not conform to W3C
                    XML specification
           Product: Xerces2-J
           Version: 2.0.0
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: SAX
        AssignedTo: xerces-j-dev@xml.apache.org
        ReportedBy: philippe.poulard@inria.fr


Hi, Mr Xerces developper,

I encountered a new bug when I tried to avoid the problem #8249.
If urn doesn't work fine in certain circumstances, I added a real file in the 
chain call.
The document contains :
    <!ENTITY % refdoc SYSTEM "urn:x-semir:RESS:dtd/refdoc.ent">
The entity resolver finds the file refdoc.ent that contains :
    <!ENTITY % ENTITIES SYSTEM "entities.ent">
    %ENTITIES;
Notice that this is a way to avoid the problem reported in bug #8249,
but, as refdoc.ent and entities.ent were put in the same folder, the SAX parser 
try to read entities.ent in the same folder as the document.
To make it work, I use a relative path from the document location to the 
entities location.
But the W3C XML specification tells that (see �4.2.2) :
".../... A URI might thus be relative to the document entity, to the entity 
containing the external DTD subset, or to some other external parameter entity."

The behaviour I obtained is not the one described in the W3C XML spec.

Best regards,
Philippe Poulard, INRIA
