Parameter entity ref incorrect in non-normalized parameter entity text

           Summary: Parameter entity ref incorrect in non-normalized
                    parameter entity text
           Product: Xerces2-J
           Version: 2.3.0
          Platform: Other
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: XNI
        AssignedTo: xerces-j-dev@xml.apache.org
        ReportedBy: mpalandri@lspeed.com


I have been using the org.apache.xerces.parsers.XMLDocumentParser class to 
parse XML documents for storage into an XML repository. To get a better idea of 
how this class calls the event methods, I extended it and just had the event 
methods generate logging output. Everything was working fine until I sent my 
parameter entity test document through and ran into what I believe is a bug.

The problem appears in the non-normalized text of an internal parameter entity 
declaration (pe2) that contains a parameter entity reference (to pe1). I 
expected the non-normalized text to merely contain the reference, but it has 
both the reference and the referenced entity's text, one after another. The 
text value is correct; It only contains the referenced entity's text and no 
entity reference.

If this isn't a problem, then how do I go about getting the entity reference 
but not the referenced entity's text in the non-normalized text? Is there some 
feature that affects this?

I have minimized the test case and it is as follows:

bug.xml
-------------------------------------------------
<!DOCTYPE foo SYSTEM "bug.dtd">
<foo/>
-------------------------------------------------

bug.dtd
-------------------------------------------------
<!ELEMENT foo EMPTY>
<!ENTITY % pe1 "This is the value of pe1">
<!ENTITY % pe2 "Entity pe2 references pe1: [%pe1;]">
-------------------------------------------------
