--
-- To identify an asset property, you must specify one of the following:
--
-- -   The @assetId@ and @propertyId@ of an asset property.
--
-- -   A @propertyAlias@, which is a data stream alias (for example,
--     @\/company\/windfarm\/3\/turbine\/7\/temperature@). To define an
--     asset property\'s alias, see
--     <https://docs.aws.amazon.com/iot-sitewise/latest/APIReference/API_UpdateAssetProperty.html UpdateAssetProperty>.
