  The <code>CreateAdditionalAssignmentsForHIT</code> operation increases the maximum number of assignments of an
  existing HIT.

  <p>
  HITs created with fewer than 10 assignments cannot be extended to have 10 or more assignments. Attempting to add
  assignments in a way that brings the total number of assignments for a HIT from fewer than 10 assignments to 10
  or more assignments will result in an <code>AWS.MechanicalTurk.InvalidMaximumAssignmentsIncrease</code>
  exception.
  </p>

  HITs that were created before July 22, 2015 cannot be extended. Attempting to extend HITs that were created
  before July 22, 2015 will result in an <code>AWS.MechanicalTurk.HITTooOldForExtension</code> exception.
