Remarks

Keys/callbacks added here will be combined with those already identified in the client object's context when signing this transaction to change the state of this account. They will not be asked to sign transactions to retrieve the record if the "WithRecord" form of the method call is made. The client will rely on the Signatory from the context to sign the transaction requesting the record.
