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.
