[dom4j-dev] namespace bug in dom4j 1.4?

[Sycheu]

I try to use dom4j 1.4 to read a xml schema and then serialize back to a file.
That schema has namespace "xs" defiened, but the serizlize output has "xs:xs:" as it namespace instead of "xs". 

I attached the source file and here is the simple problem that I am using:
     DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = dbf.newDocumentBuilder();
       
        System.out.println( "Loading document with JAXP builder: " + builder );
       
        org.w3c.dom.Document domDocument = builder.parse( "output.xsd" );
       
        org.w3c.dom.Element element2 = domDocument.getDocumentElement();
      DOMReader reader = new DOMReader();
        Document document = reader.read(domDocument);
        // use dom4j document as the source
        Source source = new DocumentSource( document );
       
        OutputFormat outformat = OutputFormat.createPrettyPrint();
 
        XMLWriter writer = new XMLWriter(System.out, outformat);
        writer.write(document);
      
        writer.flush();

Here is the output, it has "xmlns:xs" twice also in the root node.

<?xml version="1.0" encoding="UTF-8"?>

<xs:xs:schema xmlns:xs="" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-3" xmlns:xs="http://www.w3.org/2001/XMLSchema" attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-3">
  <xs:xs:import xmlns:xs="" namespace="http://schemas.xmlsoap.org/soap/envelope/" schemaLocation="http://schemas.xmlsoap.org/soap/envelope/"/>
  <xs:xs:simpleType xmlns:xs="" name="statusTextType">
    <xs:xs:annotation>
      <xs:xs:documentation>list of standard human-readable status descriptions</xs:xs:documentation>
    </xs:xs:annotation>
    <xs:xs:restriction base="xs:string"/>
  </xs:xs:simpleType>
</xs:xs:schema>

Any help is appreciated.
Thank you.
