DTCCCAPCSD1V03

supl.034.001.03

The DTCCCAPCSD1 message extends ISO corporate action movement preliminary advice cancellation advice (CAPC) message with DTCC corporate action elements not covered in the standard message.

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
%% DTCCCAPCSD1V03 recursion level 0 with max 0
DTCCCAPCSD1V03 *-- "0..1" CorporateActionGeneralInformationSD45 : CorporateActionGeneralInformation
DTCCCAPCSD1V03 *-- "0..1" FinancialInstrumentAttributesSD20 : UnderlyingSecurity
  

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

CorporateActionGeneralInformation building block

Information to be extended as supplementary data to corporate action general information. Provides additional information regarding corporate action general information. For comparison, see the ISO20022 official specification

%% CorporateActionGeneralInformationSD45 recursion level 0 with max 1

    SubEventType DTCCSubEventType8Code
}

UnderlyingSecurity building block

Information to be extended as supplementary data to underlying security details. Provides additional information regarding underlying security details. For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCAPCSD1V03 implementation follows a specific implementaiton pattern. First of all, DTCCCAPCSD1V03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCAPCSD1V03Document implements IOuterDocument. Because DTCCCAPCSD1V03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCAPCSD1V03.

classDiagram
    class IOuterRecord
    DTCCCAPCSD1V03 --|> IOuterRecord : Implements
    DTCCCAPCSD1V03Document --|> IOuterDocument~DTCCCAPCSD1V03~ : Implements
    class IOuterDocument~DTCCCAPCSD1V03~ {
        DTCCCAPCSD1V03 Message
     }
  

Document wrapper for serialization

The only real purpose DTCCCAPCSD1V03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.034.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCAPCSD1V03.ToDocument() method. The returned DTCCCAPCSD1V03Document 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:supl.034.001.03">
    <DTCCCAPCSD1>
        <CorpActnGnlInf>
            <!-- CorporateActionGeneralInformation inner content -->
        </CorpActnGnlInf>
        <UndrlygScty>
            <!-- UnderlyingSecurity inner content -->
        </UndrlygScty>
    </DTCCCAPCSD1>
</Document>
