I am not familiar with such URI resolution servers, and I wonder what it means when/if I want to process a document on my disconnected laptop computer (a common problem with DTD system IDs). Do I have to setup a server able to return the information and how simple is this operation ? It would be real nice to have a way to tell to the RDDL tools: "get the info from this local file instead of fetching it on the web". I'll borrow the second use case to W3C XML Schema. If I get a XML document from a supplier, I may want to override the location of the RDDL document provided in the document itself (because I don't trust this supplier or because I have a different way of seeing it even if it's still the same namespace). How simple would it be to do it through a URI resolution server ? A third use case is if I want to use a namespace, but I need to associate different resources than the one usually attached.
