DOMBuilder sets wrong namespace for xmlns:* attributes

           Summary: DOMBuilder sets wrong namespace for xmlns:* attributes
           Product: XalanJ2
           Version: 2.4
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xml.utils
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


SAX states that the namespace for an xmlns:* attribute should be "", however 
DOM states it should be "http://www.w3.org/2000/xmlns/";.  
org.apache.xml.utils.DOMBuilder fails to convert the namespace for these 
attributes, causing the following program to throw an exception:

org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or 
change an object in a way which is incorrect with regard to namespaces.
