-- | Attributes include the following:
--
-- -   'CustomUserData' -- arbitrary user data to associate with the
--     endpoint. Amazon SNS does not use this data. The data must be in
--     UTF-8 format and less than 2KB.
-- -   'Enabled' -- flag that enables\/disables delivery to the endpoint.
--     Amazon SNS will set this to false when a notification service
--     indicates to Amazon SNS that the endpoint is invalid. Users can set
--     it back to true, typically after updating Token.
-- -   'Token' -- device token, also referred to as a registration id, for
--     an app and mobile device. This is returned from the notification
--     service when an app and mobile device are registered with the
--     notification service.
