	// A map of attributes with their corresponding values.
	//
	// The following lists the names, descriptions, and values of the special request
	// parameters that the CreateTopic action uses:
	//
	//    * DeliveryPolicy – The policy that defines how Amazon SNS retries failed
	//    deliveries to HTTP/S endpoints.
	//
	//    * DisplayName – The display name to use for a topic with SMS subscriptions.
	//
	//    * FifoTopic – Set to true to create a FIFO topic.
	//
	//    * Policy – The policy that defines who can access your topic. By default,
	//    only the topic owner can publish or subscribe to the topic.
	//
	// The following attribute applies only to server-side-encryption (https://docs.aws.amazon.com/sns/latest/dg/sns-server-side-encryption.html):
	//
	//    * KmsMasterKeyId – The ID of an AWS-managed customer master key (CMK)
	//    for Amazon SNS or a custom CMK. For more information, see Key Terms (https://docs.aws.amazon.com/sns/latest/dg/sns-server-side-encryption.html#sse-key-terms).
	//    For more examples, see KeyId (https://docs.aws.amazon.com/kms/latest/APIReference/API_DescribeKey.html#API_DescribeKey_RequestParameters)
	//    in the AWS Key Management Service API Reference.
	//
	// The following attribute applies only to FIFO topics:
	//
	//    * ContentBasedDeduplication – Enables content-based deduplication. Amazon
	//    SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the
	//    body of the message (but not the attributes of the message).
	//
	//    * When ContentBasedDeduplication is in effect, messages with identical
	//    content sent within the deduplication interval are treated as duplicates
	//    and only one copy of the message is delivered.
	//
	//    * If the queue has ContentBasedDeduplication set, your MessageDeduplicationId
	//    overrides the generated one.
