Please help me understand this.  All elements in JDOM are created with
either the namespace, namespace + prefix you supply or the NO_NAMESPACE
namespace which is
prefix = "", uri="";

By your definition above, a default namespace is required for it to apply to
child elements with matching prefixes or no prefixes so...

<element xmlns="http://foo">
	<child1 />
	<child2 />
<element> 

would fit your scenario but in the defaul case with the NO_NAMESPACE
namespace
<element>
	<child1 />
	<child2 />
<element> 

has no default namespace so changing the namespace of <element> would not
imply a change to the children, correct?  

What I would like is concrete examples so I can write tests to confirm what
is supposed to be happening.
