    You're welcome. Each of this concept/improvement might have impacts on potentially different specification documents. If you need more information on one of these, do not hesitate to post a message. This would require too much time to do it for all elements of the list mentioned, however, doing it on a case by case is affordable.

    Cheers,
    Pascal
