I still think there is a counter-intuitive behaviour with namespaces when
creating a document. When you write:

    Element parent = new Element("parent",mynamespace);
    elemlist = new ArrayList();
    elem = new Element("child");
    elem.setText("data");
    elemlist.add(elem);
    parent.setChildren(elemlist);

You get:

    <parent xmlns:'mynamespace'><child xmlns:''>data</child></parent>

While you would expect:

    <parent xmlns:'mynamespace'><child>data</child></parent>

The fact is you expect mynamespace to become the default namespace for all
the tree below parent. But in order to get what you expect, you need to
write:

    Element parent = new Element("parent",mynamespace);
    elemlist = new ArrayList();
    elem = new Element("child"",mynamespace); // specify ns for each child
    elem.setText("data");
    elemlist.add(elem);
    parent.setChildren(elemlist);

Is this really the intended behaviour ? Someone said on this list there was
a default namespace when creating documents too. How does this work ?
