I think you might have missed the point. I don't see any additional coupling in a system where a data-source (DB, directory, whatever) provides an XML interface for the interchange of data directly to the client via DOM, without XML actually ever having existed as a transmission medium. I'm not thinking Internet and I'm not thinking distribution. XML is getting used everywhere and is not limited to distributed applications. I'm thinking more about a loosely coupled system where data is exchanged between server and middle-ware via XML INSTEAD of CORBA/DCOM. Objects and their associations/relationships are modelled using XML schemae which are specific to the project and not using some general mechanism like SOAP/XML-RPC. It just seems to me to be (more than) a little bit of a waste of time for a server to generate XML within such as system, pass it back to the caller and for the consumer to not actually look at it directly, but rather use a standardized interface such as DOM. You have the overhead of generating the XML on the server and parsing it on the receiving end. Within such a system, the data consumer could do EXACTLY the same thing by just accessing a DOM interface on the server. The DOM would be dynamically built directly from the underlying storage/objects/data rather than generating XML as an intermediary step. If the consumer wanted an actual XML document then he could create it using the DOM as per usual. Neither the server nor the client are more tightly coupled with any other part of the system as a result. 'twas just a thought...
