  The integer value to compare against the Qualification's value. IntegerValue must not be present if Comparator is
  Exists or DoesNotExist. IntegerValue can only be used if the Qualification type has an integer value; it cannot
  be used with the Worker_Locale QualificationType ID. When performing a set comparison by using the In or the
  NotIn comparator, you can use up to 15 IntegerValue elements in a QualificationRequirement data structure.
