    This function is called in every Copy-Ctor for copying the attributes.
    The latter can be only copied as soon as the derived class exists since
    for setting them the Which() function is called and that has the default
    value of 0 in the base class and is then overridden by the derived class.

    If we copy over multiple documents then the new document has to be provided
    in which <this> is defined. Currently this is important for DropCaps
    because that contains data that needs to be copied deeply.
