DTCCCARESD1V04

supl.025.001.04

The DTCCCARESD1 message extends ISO corporate action movement reversal advice 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
%% DTCCCARESD1V04 recursion level 0 with max 0
DTCCCARESD1V04 *-- "0..1" CorporateActionGeneralInformationSD53 : CorporateActionGeneralInformation
DTCCCARESD1V04 *-- "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

   direction tb
%% CorporateActionGeneralInformationSD53 recursion level 0 with max 1

    PlaceAndName IsoMax350Text
    EventGroup EventGroup3Code
    SubEventType DTCCSubEventType10Code
}
  

CorporateActionGeneralInformationSD53 members

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

%% FinancialInstrumentAttributesSD20 recursion level 0 with max 1

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCARESD1V04 implementation follows a specific implementaiton pattern. First of all, DTCCCARESD1V04 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCARESD1V04Document implements IOuterDocument. Because DTCCCARESD1V04 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCARESD1V04.

classDiagram
    class IOuterRecord
    DTCCCARESD1V04 --|> IOuterRecord : Implements
    DTCCCARESD1V04Document --|> IOuterDocument~DTCCCARESD1V04~ : Implements
    class IOuterDocument~DTCCCARESD1V04~ {
        DTCCCARESD1V04 Message
     }
  

Document wrapper for serialization

The only real purpose DTCCCARESD1V04Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.025.001.04’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCARESD1V04.ToDocument() method. The returned DTCCCARESD1V04Document 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.025.001.04">
    <DTCCCARESD1>
        <CorpActnGnlInf>
            <!-- CorporateActionGeneralInformation inner content -->
        </CorpActnGnlInf>
        <UndrlygScty>
            <!-- UnderlyingSecurity inner content -->
        </UndrlygScty>
    </DTCCCARESD1>
</Document>
