The AcceptorDiagnosticResponse message is sent by the acquirer (or its agent) to provide to the acceptor the result of the diagnostic request.
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.

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the AcceptorDiagnosticResponseV02 implementation follows a specific implementaiton pattern. First of all, AcceptorDiagnosticResponseV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorDiagnosticResponseV02Document implements IOuterDocument. Because AcceptorDiagnosticResponseV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorDiagnosticResponseV02.

class IOuterRecord
AcceptorDiagnosticResponseV02 --|> IOuterRecord : Implements
AcceptorDiagnosticResponseV02Document --|> IOuterDocument~AcceptorDiagnosticResponseV02~ : Implements
class IOuterDocument~AcceptorDiagnosticResponseV02~ {
AcceptorDiagnosticResponseV02 Message
}
Document wrapper for serialization
The only real purpose AcceptorDiagnosticResponseV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.014.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorDiagnosticResponseV02.ToDocument() method. The returned AcceptorDiagnosticResponseV02Document value will serialize correctly according to ISO 20022 standards.
