-- | 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.
