	//   - ConfirmationWasAuthenticated – true if the subscription confirmation request
	//   was authenticated.
	//
	//   - DeliveryPolicy – The JSON serialization of the subscription's delivery
	//   policy.
	//
	//   - EffectiveDeliveryPolicy – The JSON serialization of the effective delivery
	//   policy that takes into account the topic delivery policy and account system
	//   defaults.
	//
	//   - FilterPolicy – The filter policy JSON that is assigned to the subscription.
	//   For more information, see [Amazon SNS Message Filtering]in the Amazon SNS Developer Guide.
	//
	//   - FilterPolicyScope – This attribute lets you choose the filtering scope by
	//   using one of the following string value types:
	//
	//   - MessageAttributes (default) – The filter is applied on the message
	//   attributes.
	//
	//   - MessageBody – The filter is applied on the message body.
	//
	//   - Owner – The Amazon Web Services account ID of the subscription's owner.
	//
	//   - PendingConfirmation – true if the subscription hasn't been confirmed. To
	//   confirm a pending subscription, call the ConfirmSubscription action with a
	//   confirmation token.
	//
	//   - RawMessageDelivery – true if raw message delivery is enabled for the
	//   subscription. Raw messages are free of JSON formatting and can be sent to HTTP/S
	//   and Amazon SQS endpoints.
	//
	//   - RedrivePolicy – When specified, sends undeliverable messages to the
	//   specified Amazon SQS dead-letter queue. Messages that can't be delivered due to
	//   client errors (for example, when the subscribed endpoint is unreachable) or
	//   server errors (for example, when the service that powers the subscribed endpoint
	//   becomes unavailable) are held in the dead-letter queue for further analysis or
	//   reprocessing.
	//
	//   - SubscriptionArn – The subscription's ARN.
	//
	//   - TopicArn – The topic ARN that the subscription is associated with.
	//
	// The following attribute applies only to Amazon Data Firehose delivery stream
	// subscriptions:
	//
	//   - SubscriptionRoleArn – The ARN of the IAM role that has the following:
	//
	//   - Permission to write to the Firehose delivery stream
	//
	//   - Amazon SNS listed as a trusted entity
	//
	// Specifying a valid ARN for this attribute is required for Firehose delivery
	//   stream subscriptions. For more information, see [Fanout to Firehose delivery streams]in the Amazon SNS Developer
	//   Guide.
