-- * 'dmwetFilters' - Optional filters used to scope down the returned tasks. The supported filter key is STATUS with the corresponding values PENDING, IN_PROGRESS, SUCCESS, FAILED, TIMED_OUT, CANCELLING, and CANCELLED.
--
-- * 'dmwetNextToken' - The token for the next set of items to return. (You received this token from a previous call.)
--
-- * 'dmwetMaxResults' - The maximum number of items to return for this call. The call also returns a token that you can specify in a subsequent call to get the next set of results.
--
-- * 'dmwetWindowExecutionId' - The ID of the Maintenance Window execution whose task executions should be retrieved.
