xmlhack: IETF drafts on URIs

As the IETF prepares for its meeting in Pittsburgh, it released additional drafts (1 2 3 4) on URI processing and creation.

A URN Namespace for Norman Walsh - Norman Walsh, of DocBook fame, requests his own personal URN namespace so that he can create identifiers like "urn:ndw:doctypes:slides:1.25" for use in XML. To support them, "The owner will distribute catalogs (e.g., OASIS Open TR9401 Catalogs) that map the subset of URNs considered useful to resource identifiers (e.g., URLs). In addition, the owner will provide an online resolution service based on RFC2483."
URI Resolution using the Dynamic Delegation Discovery System - Describes the resolution of URNs with the "Dynamic Delegation Discovery System (DDDS)", a system capable of handling many more per-resource records than DNS.
The 'go' URI Scheme for the Common Name Resolution Protocol - This draft describes a URI scheme which provides "a simplified query syntax that is a subset of what is available via the XML" for another protocol, CNRP.
A URN Namespace of Object Identifiers - Revises an earlier draft describing how organizations can use enterprise numbers assigned by the IANA to create URNs they know are unique.
