The namespace URI property of an element or attribute node can be null,
meaning that the element or attribute is "not in a namespace". What I'm
saying is that it's often more convenient to regard such elements/attributes
as being in a namespace, a namespace with no name, and Elliotte's model
which you quoted seems to treat them that way.
