Further to this argument - managing URIs within a domain is largely self
enforcing when the URI resolves directly or indirectly to a concrete
resource - management is done implicitly. When the requirement is simply
to reserve a worldwide unique name, enforcing the mechanism is an
explicit management task - because of this the infrastructure may well
not exist at all and is certainly open to errors and abuses.
