I have a quibble with this terminology. URLs need not be location dependent. This is a function of the URL scheme or namespace. For example suppose we invent a new location independent protocol (LIP): "lip:W3C/Specifications/XSLT/Version1.0" or: "FPI: ...." This would be a location independent URL. The idea remains that URLs are URIs used to "locate" resources. If you overload the "urn" scheme with a network protocol, it really becomes a URL regardless of its definition in 2141. > >Conclusion: >URN brings more longevity to information elements contained in the published >document.
