-- The @ListQualificationRequests@ operation retrieves requests for
-- Qualifications of a particular Qualification type. The owner of the
-- Qualification type calls this operation to poll for pending requests,
-- and accepts them using the AcceptQualification operation.
--
-- This operation returns paginated results.
