AcceptorDiagnosticResponseV03

caaa.014.001.03

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

%% AcceptorDiagnosticResponseV03 recursion level 0 with max 0

AcceptorDiagnosticResponseV03 *-- "1..1" AcceptorDiagnosticResponse3 : DiagnosticResponse

Now, we will zero-in one-by-one on each of these building blocks.

Header building block

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the AcceptorDiagnosticResponseV03 implementation follows a specific implementaiton pattern. First of all, AcceptorDiagnosticResponseV03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorDiagnosticResponseV03Document implements IOuterDocument. Because AcceptorDiagnosticResponseV03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorDiagnosticResponseV03.

classDiagram
    class IOuterRecord
    AcceptorDiagnosticResponseV03 --|> IOuterRecord : Implements
    AcceptorDiagnosticResponseV03Document --|> IOuterDocument~AcceptorDiagnosticResponseV03~ : Implements
    class IOuterDocument~AcceptorDiagnosticResponseV03~ {
        AcceptorDiagnosticResponseV03 Message
     }
  

Document wrapper for serialization

The only real purpose AcceptorDiagnosticResponseV03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.014.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorDiagnosticResponseV03.ToDocument() method. The returned AcceptorDiagnosticResponseV03Document value will serialize correctly according to ISO 20022 standards.

Sample of message format

This is an abbreviated version of what the message should look like.

<Document xmlns="urn:iso:std:iso:20022:tech:xsd:caaa.014.001.03">
    <AccptrDgnstcRspn>
        <Hdr>
            <!-- Header inner content -->
        </Hdr>
        <DgnstcRspn>
            <!-- DiagnosticResponse inner content -->
        </DgnstcRspn>
        <SctyTrlr>
            <!-- SecurityTrailer inner content -->
