   6 select a value from a bounded range of values.

   9 <para>
  10 #AtkValue should be implemented for components which either display a
  11 value from a bounded range, or which allow the user to specify a value
  12 from a bounded range, or both.  For instance, most sliders and range
  13 controls, as well as dials, should have #AtkObject representations which
  14 implement #AtkValue on the component's behalf.  #AtKValues may be
  15 read-only, in which case attempts to alter the value return FALSE to
  16 indicate failure.
