-- Gets information about the traffic policy instances that you created in
-- a specified hosted zone.
--
-- After you submit an 'UpdateTrafficPolicyInstance' request, there\'s a
-- brief delay while Amazon Route 53 creates the resource record sets that
-- are specified in the traffic policy definition. For more information,
-- see the State response element.
--
-- To get information about the traffic policy instances that you created
-- in a specified hosted zone, send a 'GET' request to the
-- '2013-04-01\/trafficpolicyinstance' resource and include the ID of the
-- hosted zone.
--
-- Amazon Route 53 returns a maximum of 100 items in each response. If you
-- have a lot of traffic policy instances, you can use the 'MaxItems'
-- parameter to list them in groups of up to 100.
--
-- The response includes four values that help you navigate from one group
-- of 'MaxItems' traffic policy instances to the next:
--
-- -   __IsTruncated__
-- -   __MaxItems__
-- -   __TrafficPolicyInstanceNameMarker__ and
--     __TrafficPolicyInstanceTypeMarker__
