The AcceptorCancellationAdvice message is sent by an acceptor (or its agent) to notify the acquirer (or its agent) of the cancellation of a successfully completed transaction. The transaction has been completed without financial transfer, or the acceptor is aware that the transaction was not cleared by the acquirer.
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 AcceptorCancellationAdviceV08 implementation follows a specific implementaiton pattern. First of all, AcceptorCancellationAdviceV08 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorCancellationAdviceV08Document implements IOuterDocument. Because AcceptorCancellationAdviceV08 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorCancellationAdviceV08.

class IOuterDocument~AcceptorCancellationAdviceV08~ {
AcceptorCancellationAdviceV08 Message
}
Document wrapper for serialization
The only real purpose AcceptorCancellationAdviceV08Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.007.001.08’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorCancellationAdviceV08.ToDocument() method. The returned AcceptorCancellationAdviceV08Document value will serialize correctly according to ISO 20022 standards.
