-- Returns the estimated number of activity tasks in the specified task
-- list. The count returned is an approximation and isn\'t guaranteed to be
-- exact. If you specify a task list that no activity task was ever
-- scheduled in then @0@ is returned.
--
-- __Access Control__
--
-- You can use IAM policies to control this action\'s access to Amazon SWF
-- resources as follows:
--
-- -   Use a @Resource@ element with the domain name to limit the action to
--     only specified domains.
--
-- -   Use an @Action@ element to allow or deny permission to call this
--     action.
--
-- -   Constrain the @taskList.name@ parameter by using a @Condition@
--     element with the @swf:taskList.name@ key to allow the action to
--     access only certain task lists.
--
-- If the caller doesn\'t have sufficient permissions to invoke the action,
-- or the parameter values fall outside the specified constraints, the
-- action fails. The associated event attribute\'s @cause@ parameter is set
-- to @OPERATION_NOT_PERMITTED@. For details and example IAM policies, see
-- <https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html Using IAM to Manage Access to Amazon SWF Workflows>
-- in the /Amazon SWF Developer Guide/.
