    FYI:

    Just checked in a few updates to our DTD files.

    1. I renamed all DTD files to start with "cayenne-" and end with
    version identifier, like "x_x.dtd". This would allow us to keep track
    of the official DTD version changes, and creates a primitive namespace
    for them.

    2. I added a new "query" element to the cayenne-data-map.dtd. A trimmed
    diff with 1.0 version is attached below. The actual implementation of
    this element is coming very soon. For qualifier encoding it takes
    advantage of the yet unreleased (but already checked in) expression
    parser. Any comments on "query"?
