The notion arises where one attempts to maintain the prefix information with
the DOM element (for example, by virtue of making it available in the
interface to the element's identifier). Some people maintain that this, in
itself, is a mistake. Others believe that such a feature is indispensible.
Were it truly indispensible, it would introduce scoping issues into the DOM model.

The key is that one can no longer think of it as sticking 'a new "f" element' anywhere.
One is permitted to add only "a.b.c:f" elements, or the like. That is, unless
one recognizes the legitimacy of the "null" namespace and the intent is to add
an element of which the identifier is "in" that namespace.
