    Sun is working on a similar solution. The project is called "Adelard",
    and the concept is called "data binding". At, there is another
    solution called Quick. It uses its own schema at the moment, but could
    be revised to use others. That's and interesting model because, instead
    of compiling a schema to make classes that contain XML-aware code,
    the XML-awareness stays separate. That lets him use it with existing

    As I say, its an interesting approach, but there is little to no usable
    explanation on the web site. I got that information from a phone
    conversation. The author is very pleasant, and I suspect his approach
    is reasonable, but sheer inability to communicate it is going to limit
    its acceptance.
