Hello, on the basis of experiences gathered during the revision of ISBN and NBN namespace registration requests, the revised text below works fine. It is important to include changes both in namespace management processes and in underlying technologies, since a technological change may have a major impact on the management of the namespace (for instance, a change in the syntax of the identifier may alter the way in which the URNs can be resolved).
