    Hi Ari,

    thanks for pointing to that dev discussion thread. I was going to do
    the same. In fact my own interest in this approach started as a result
    of David posting his first example:

        https://issues.apache.org/cayenne/browse/CAY-877

    And I hope to reuse his work if possible (and at the minimum use some
    of the ideas).

    Andrus
