The AcceptorCancellationResponse message is sent by the acquirer (or its agent) to an acceptor (or its agent), to return the outcome of the cancellation request. If the response is positive, the acquirer has voided the financial data from the captured transaction.
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

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the AcceptorCancellationResponseV08 implementation follows a specific implementaiton pattern. First of all, AcceptorCancellationResponseV08 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCancellationResponseV08Document implements IOuterDocument. Because AcceptorCancellationResponseV08 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCancellationResponseV08.

class IOuterDocument~AcceptorCancellationResponseV08~ {
AcceptorCancellationResponseV08 Message
}
Document wrapper for serialization
The only real purpose AcceptorCancellationResponseV08Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.006.001.08’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCancellationResponseV08.ToDocument() method. The returned AcceptorCancellationResponseV08Document value will serialize correctly according to ISO 20022 standards.
