What happened to attribute namespace declaration

Question

Hi,
The code below:
public class XMLWriter {
     public static void writeXML() throws TransformerFactoryConfigurationError,
               TransformerConfigurationException, SAXException {
          SAXTransformerFactory tf = (SAXTransformerFactory) SAXTransformerFactory
                    .newInstance();
          tf.setAttribute("indent-number", Integer.valueOf(4));
          TransformerHandler hd = tf.newTransformerHandler();          
          Transformer t = hd.getTransformer();
          t.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
          t.setOutputProperty(OutputKeys.METHOD, "xml");
          t.setOutputProperty(OutputKeys.INDENT, "yes");
          hd.setResult(new StreamResult(new OutputStreamWriter(System.out)));
          AttributesImpl atts = new AttributesImpl();
          atts.addAttribute("http://attribs.com/attImpl", "attribOne", "someNamespace:attribOne", "string",
                    "someValue");          
          hd.startDocument();
          hd.startElement("http://example.com", "tag", "a:tag", atts);
          hd.endElement("http://example.com/a", "tag", "a:tag");
          hd.endDocument();
     public static void main(String[] args) {
          try {
               writeXML();
          } catch (Exception e) {
               e.printStackTrace();
}produces the following output (using JRE 1.6.0_01):
<?xml version="1.0" encoding="UTF-8"?>
<a:tag xmlns:a="http://example.com" someNamespace:attribOne="someValue"/>but where's the namespace declaration for someNamespace? What to do to make sure that the namespace declaration for an attribute is included in the output.
Regards,

Thank you, that works just fine,
it's a shame though that TransformerHandler is capable of generating namespace declatarion for Element but not it's attributes.
