Hello Ramesh,
You wrote:
"I prefer to get this code with work with dummy XSLT transformer so that I do not have to use native Xerces API. Instead, my code will only use JAXP interface and everything happens behind the scenes."

When I used the dummy XSLT transformer from the java class you provided, I got following output with Xalan 2.6.0 (currentCVS).

Serialize With Dummy Transform:
<?xml version="1.0" encoding="UTF-8"?>
<mspm:rootelement xmlns:mspm="http://rsakala">
   <mspm:element mspm2:mspm2attr2="attrvalue2" mspm:mspmattr1="attrvalue1"/>
</mspm:rootelement>

Is this expected behaviour?
Thanks!

    Summary: I cannot use dummy transform technique to serialize a document with namespaces
       Type: Bug

     Status: Open

    Project: XalanJ2
 Components: 
             JAXP
   Versions:
             2.4

Description:
I am creating a DOM document with JAXP interface with namespace elements and 
attributes. I am seeing different behavior with different versions of Xerces 
versions; None of them except version 2.0.1 seems to be correct.

With version 2.3.0 and 2.2.1:
If I use XMLSerializer, I do not get the namespace attributes.
If I use the DOM3 procedure, I get the namespace attributes; but all of the 
elements have the namespace attributes unnecessarily instead of having it once 
on the root node.
If I use a dummy XSLT transformer with DOM source and Stream result, I do not 
get any namespace nodes.

With version 2.0.1:
If I use XMLSerializer, I get the namespace attributes properly.
If I use a dummy XSLT transformer with DOM source and Stream result, I do not 
get any namespace nodes.

I prefer to get this code with work with dummy XSLT transformer so that I do 
not have to use native Xerces API. Instead, my code will only use JAXP 
interface and everything happens behind the scenes.

I have attached the code I wrote below.

Here is exact result I am seeing with different xerces parsers.

With Xerces2.0.1.jar, I see the following in System.out
