Duplicate "xmlns" attributes

Hello,

I encountered a suspicious phenomenon of Xalan-j 2.7.1.
When I parsed the XML below with Xalan-j 2.7.1, using getAttributes 
method of Node A, I got 2 "xmlns" attributes in the result.
There should be only 1 "xmlns" attribute in the result, I suppose.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE A [
	<!ATTLIST A xmlns CDATA #FIXED 'http://test.xmlns.com/test#'>
]>
<A>
  <A1>test</A1>
</A>

For example, if I build and run the attached program (Test.java), 
I get the result below. (2 xmlns attributes)

Attr 0:
 NodeName  = xmlns
 NodeValue = http://test.xmlns.com/test#
 NameSpace = http://www.w3.org/2000/xmlns/
Attr 1:
 NodeName  = xmlns
 NodeValue = http://test.xmlns.com/test#
 NameSpace = null

But expected result is:

Attr 0:
 NodeName  = xmlns
 NodeValue = http://test.xmlns.com/test#
 NameSpace = http://www.w3.org/2000/xmlns/

This problem occurred only when I use Xalan-j 2.7.1.
When I use Xalan-j 2.7.0, this problem never occurs.

Is there anyone who knows about this problem?
Is there any workaround?

I have attached the sample program and the XML file.
(Please add the path of xalan.jar(2.7.1) to CLASSPATH.)

My test environment is below:
  Java : jdk1.6.0 update 12
  Xalan: Xalan-j 2.7.1 (Xerces 2.9.0)
  OS   : Windows XP

Thanks,
Masanori Hayashi
