There is no such thing as a default Namespace for a document.  The same
document could have 20 things called "default namespaces".  So when you
call

new Element("foo");

Just which namespace would you have that element be in?  You can't know
at construction!  

You could have it depend on where you later place the element, but as
XML experts will tell you, an element's namespace is intrinsic to that
element and should not change depending on location, and elements should
not have to be namespace-less if they aren't in a document.

Think of "default namespace" as "no-prefix namespace" and it makes easy
sense.
