The AcceptorCancellationAdviceResponse message is sent by the acquirer (or its agent) to acknowledge the acceptor (or its agent) about the notification of the payment cancellation.
Message Construction
Every ISO20022 message has at the highest level what we call ‘building blocks’. Because the message is constructed as immutable records, the association is by composition. Below you can see the relationship between the message and its constituent building blocks: For comparison, see the ISO20022 official specification

Now, we will zero-in one-by-one on each of these building blocks.
Header building block
Cancellation advice response message management information. Set of characteristics related to the protocol. For comparison, see the ISO20022 official specification

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the AcceptorCancellationAdviceResponseV02 implementation follows a specific implementaiton pattern. First of all, AcceptorCancellationAdviceResponseV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCancellationAdviceResponseV02Document implements IOuterDocument. Because AcceptorCancellationAdviceResponseV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCancellationAdviceResponseV02.
classDiagram class IOuterRecord AcceptorCancellationAdviceResponseV02 --|> IOuterRecord : Implements AcceptorCancellationAdviceResponseV02Document --|> IOuterDocument~AcceptorCancellationAdviceResponseV02~ : Implements class IOuterDocument~AcceptorCancellationAdviceResponseV02~ { AcceptorCancellationAdviceResponseV02 Message }
Document wrapper for serialization
The only real purpose AcceptorCancellationAdviceResponseV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.008.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCancellationAdviceResponseV02.ToDocument() method. The returned AcceptorCancellationAdviceResponseV02Document value will serialize correctly according to ISO 20022 standards.
