But this is not a decisive case, because a namespace name used in a single
document will give the same identity function whether it is taken as a literal
string or a relative URI reference.

The crucial case is two documents both of which have xmlns:foo="foo"
declarations.  Do they declare the same namespace (the "literal" interpretation),
different namespaces (the "absolutize" interpretation) or nothing at all
(the "forbid" interpretation)?

Which also supposedly breaks Microsoft's customers' documents.
