Sandra, I can give two reasons to have a DTD anyway: First, at design & code time, it provides a formal schema which acts as a contract between all the users and creators of the documents -- if all documents created are valid, and all readers can read any valid document, then your system will work. Second, your quality argument: If these documents are created by people, then you really need to validate to prevent simple human error. Even if the docs are machine generated, in a medical application, being paranoid about a change to one side not being picked up on the other sounds like a good ideal.
