To the extent there is no conflict of interest between the holder of a limited testamentary power of appointment or a presently exercisable limited power of appointment and the persons represented with respect to the particular question or dispute, the holder may also represent and bind persons whose interests as possible appointees are subject to the power. The rights of the holder of a presently exercisable general power of appointment are governed by section 5806.03 of the Revised Code.
