Why do you think that using a URI necessarily requires a Internet connection?
A URI is only an identifier, made unique using either a global registry or using
some other methods (an URI can contain a UUID too, or a SGML public ID, or any
other identifier schemes).
My point is that, if such private agreement exist between private users, they
must have exchanged in some way their agreement. A part of this exchange may be
as well a set of data files, and in fact it is waht is then expected when they
will want to interchange their own private data.
A URI is not restricted to Internet and even if it's a active URL which can be
dereferenced on the Internet, there's no requirement to do so. Look for example
about the SGML public identifiers that are used to indicate document types. Most
browsers will (and should) recognize those identifiers and will resolve them
locally if this URI is mapped into a local registry of known schemas, without
needing to retreive the DTD from that URL. Do you know SAX Entity Resolvers?
Same analogy for the XML namespaces.
Consider then this URI as a namespace with no required dereference and you're
done.
