There is no null namespace. We can say that the namespace of a name is
null, meaning that the name is in no namespace; but it is wrong to say
that the name is in the null namespace, because there is no such thing.
Of course, there is a set of names containing all names that are in no
namespace, and since a namespace is essentially a set of names (despite
the assertion of the Namespaces REC to the contrary), it would have been
easy and elegant to define this set as a namespace; but the spec chose
not to do that. Every namespace is a set of names, but not every set of
names is a namespace.
