CreateMitBatchTransactionResponse
Per-entry creation results for a MIT batch request.
Results for each submitted transaction in the batch, in the same order as received. Each transaction is processed individually, if the transaction passes initial validation then a transaction is created for background processing and a `transaction` is returned. If the initial validation fails, instead an `error` is returned.
Outcome for a single entry in a MIT batch request. Only one of `transaction` or `error` is populated.
