// * EffectiveDeliveryPolicy – The JSON serialization of the effective

//
// 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 Amazon Web Services managed customer master key

// * FifoTopic –

//
// * ContentBasedDeduplication
// – Enables content-based deduplication for FIFO topics.
//
// * By default,
// ContentBasedDeduplication is set to false. If you create a FIFO topic and this

//
// * When
// you set ContentBasedDeduplication to true, Amazon SNS uses a SHA-256 hash to

// attributes of the message). (Optional) To override the generated value, you can
// specify a value for the MessageDeduplicationId parameter for the Publish action.
