Section 10-3.1. Powers of appointment and other powers

(a)  This  article  applies  to  powers  of  appointment.  A  power of
  appointment, as the term is  used  in  this  article,  is  an  authority
  created  or  reserved  by  a  person  having  property  subject  to  his
  disposition, enabling the donee to designate, within such limits as  may
  be prescribed by the donor, the appointees of the property or the shares
  or the manner in which such property shall be received.
    (b) This article applies, generally, to powers which are not powers of
  appointment,  such as a power to revoke a disposition previously made, a
  power during minority to manage property vested in an infant, a power to
  disburse the principal of a trust, a power to sell in a mortgage  and  a
  power in a life tenant to make leases. This enumeration is not exclusive
  but illustrative.
