DTCCCAPSSD1V04

supl.010.001.04

The DTCCCAPSSD1 message extends ISO corporate action event processing status 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

%% DTCCCAPSSD1V04 recursion level 0 with max 0
DTCCCAPSSD1V04 *-- "0..1" CorporateActionGeneralInformationSD20 : CorporateActionGeneralInformation
DTCCCAPSSD1V04 *-- "0..1" CorporateActionSD9 : CorporateActionDetails

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

CorporateActionGeneralInformation building block

Extension block for the information to be extended as corporate action general information. Provides additional information regarding corporate action general information. For comparison, see the ISO20022 official specification

LotteryType	Specifies the type of lottery announced.	LotteryType1Code - Optional 0..1

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCAPSSD1V04 implementation follows a specific implementaiton pattern. First of all, DTCCCAPSSD1V04 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCAPSSD1V04Document implements IOuterDocument. Because DTCCCAPSSD1V04 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCAPSSD1V04.

classDiagram
    class IOuterRecord
    DTCCCAPSSD1V04 --|> IOuterRecord : Implements
    DTCCCAPSSD1V04Document --|> IOuterDocument~DTCCCAPSSD1V04~ : Implements
    class IOuterDocument~DTCCCAPSSD1V04~ {
        DTCCCAPSSD1V04 Message
     }

Document wrapper for serialization

The only real purpose DTCCCAPSSD1V04Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.010.001.04’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCAPSSD1V04.ToDocument() method. The returned DTCCCAPSSD1V04Document 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.010.001.04">
    <DTCCCAPSSD1>
        <CorpActnGnlInf>
            <!-- CorporateActionGeneralInformation inner content -->
        </CorpActnGnlInf>
        <CorpActnDtls>
            <!-- CorporateActionDetails inner content -->
        </CorpActnDtls>
    </DTCCCAPSSD1>
