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. Michael Kay Software AG home: Michael.H.Kay@n... work: Michael.Kay@s...
