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
classDiagram direction LR %% AcceptorDiagnosticResponseV04 recursion level 0 with max 0 AcceptorDiagnosticResponseV04 *-- "1..1" Header10 : Header AcceptorDiagnosticResponseV04 *-- "1..1" AcceptorDiagnosticResponse4 : DiagnosticResponse AcceptorDiagnosticResponseV04 *-- "1..1" ContentInformationType11 : SecurityTrailer
Now, we will zero-in one-by-one on each of these building blocks.
Header building block
Diagnostic 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 AcceptorDiagnosticResponseV04 implementation follows a specific implementaiton pattern. First of all, AcceptorDiagnosticResponseV04 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorDiagnosticResponseV04Document implements IOuterDocument. Because AcceptorDiagnosticResponseV04 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorDiagnosticResponseV04.
classDiagram class IOuterRecord AcceptorDiagnosticResponseV04 --|> IOuterRecord : Implements AcceptorDiagnosticResponseV04Document --|> IOuterDocument~AcceptorDiagnosticResponseV04~ : Implements class IOuterDocument~AcceptorDiagnosticResponseV04~ { AcceptorDiagnosticResponseV04 Message }
Document wrapper for serialization
The only real purpose AcceptorDiagnosticResponseV04Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.014.001.04’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorDiagnosticResponseV04.ToDocument() method. The returned AcceptorDiagnosticResponseV04Document value will serialize correctly according to ISO 20022 standards.
