        Reads the 'next' element and returns an object constructed out of it,
        if at all possible. The object construction is dispatched to
        subclasses (via next_object). If the object construction fails,
        next_object should return None.

        This method would consume subsequent XML elements/subtrees until a
        suitable object can be constructed or we run out of XML elements. In
        the latter case StopIteration is thrown (as per iterator protocol).

        IVR 2007-12-25 TBD: releasing the memory occupied by subtrees is quite
        helpful, but very ugly in this code. This should be implemented more
        elegantly.
