Xalan 2.2.D11 adds a strange Attribute

Hi all,
dear Myriam,

A bug in Xalan v.2.2D11 in the namespace behaviour. To demonstrate this bug, 
the following XML file is converted to a NodeSet using the XPathAPI and then, 
all Nodes in the node set are printed out. In Version D10, it's the correct 
size, in D11, a curious 
org.apache.xml.dtm.ref.dom2dtm.DOM2DTM$defaultNamespaceDeclarationNode 
Attribute is added to the tree. 


The XML File:
<?xml version=\1.0"?>
<!DOCTYPE doc [
<!ELEMENT doc (n+)>
<!ELEMENT n (#PCDATA)>
]>
<!-- full document with decl -->
<doc><n>1</n></doc>



The XPath used for Selection:
(.//. | .//@* | .//namespace::*)

Output from both versions:

Apache Xerces Xerces 1.4.3
Apache Xalan  Xalan Java 2.2.D10
0 DOCUMENT [#document: null]
1 COMMENT [#comment:  full document with decl ]
2 ELEMENT [doc: null]
3 ELEMENT [n: null]
4 TEXT_NODE [#text: 1]

Apache Xerces Xerces 1.4.3
Apache Xalan  Xalan Java 2.2.D11
0 DOCUMENT [#document: null]
1 COMMENT [#comment:  full document with decl ]
2 ELEMENT [doc: null]
3 ATTRIBUTE 
org.apache.xml.dtm.ref.dom2dtm.DOM2DTM$defaultNamespaceDeclarationNode@6b017e
4 ELEMENT [n: null]
5 TEXT_NODE [#text: 1]
