Question regarding object composition

[FrankV01]

Is there a reason that you put State in to object StateMap rather than just putting all the properties in to AlexAudioState? Is this required by DynamoDB or is this your design choice?

[DynamoDBTable("AlexaAudioStates")]
    public class AlexaAudioState
    {
        [DynamoDBHashKey]
        public string UserId { get; set; }
        public StateMap State { get; set; }

    }
