DOM2Writer doesn't treat the "xml" namspace specially

           Summary: DOM2Writer doesn't treat the "xml" namspace specially
           Product: Axis
           Version: current (nightly)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Serialization/Deserialization
        AssignedTo: axis-dev@xml.apache.org
        ReportedBy: pratik.datta@peregrine.com


The namespace "xml" is a special namespace. Lot of tools (especially 
Microsoft's .NET wsdl.exe) cannot parse an xml document having an explict 
declaration for the xml namespace.

For example if I have an XML document like this

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://tempuri.org" xmlns="http://tempuri.org" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:annotation>
 <xsd:documentation xml:lang="en">
   Purchase order schema for Example.com.
   Copyright 2000 Example.com. All rights reserved.
  </xsd:documentation>
</xsd:annotation>
</xsd:schema>


Notice how the xml:lang="en" attribute uses the xml namespace without declaring 
what xml namespace really is. This is perfectly valid. Some tools will give an 
error if the namespace declaration exists. 

When I parse this xml and serialize it back using the DOM2Writer, it makes it 
like this:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://tempuri.org" xmlns="http://tempuri.org" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:annotation>
   <xsd:documentation xml:lang="en" 
xmlns:xml="http://www.w3.org/XML/1998/namespace">
   Purchase order schema for Example.com.
   Copyright 2000 Example.com. All rights reserved.
    </xsd:documentation>
  </xsd:annotation>
</xsd:schema>

The explicit declaration of xmlns:xml="http://www.w3.org/XML/1998/namespace" 
causes problems with wsdl.exe.

Can you fix this problem?

Thanks
