The following

       DocumentBuilderFactory documentBuilderFactory = 
DocumentBuilderFactory.newInstance();
       documentBuilderFactory.setNamespaceAware(true);
       DocumentBuilder documentBuilder = 
documentBuilderFactory.newDocumentBuilder();
       Document xmlDocument = 
documentBuilder.getDOMImplementation().createDocument(
         "http://www.w3.org/1999/xhtml",
         "html",
         null
       );
       Element rootElement = xmlDocument.getDocumentElement();
 
rootElement.setAttributeNS("http://www.w3.org/XML/1998/namespace", 
"xml:lang", "en");

       System.out.println("xmlDocument class: " + 
xmlDocument.getClass().getName());
       System.out.println("Serialized document:");
       System.out.println(serializeToString(xmlDocument));

run with Java 1.5 gives

xmlDocument class: com.sun.org.apache.xerces.internal.dom.DocumentImpl
Serialized document:
<html xml:lang="en" xmlns="http://www.w3.org/1999/xhtml"></html>

which looks fine, namespace declarations and prefixes are there.

Run with Java 1.4 however I get:

xmlDocument class: org.apache.crimson.tree.XmlDocument
Serialized document:
<?xml version="1.0" encoding="UTF-8"?>
<html xml:lang="en"/>

so you might have hit a bug with the DOM or Transformer implementation 
you are using respectively which is on your classpath.
