DTCCCAISSD1V01

supl.030.001.01

The DTCCCAISSD1 message extends ISO Corporate Action Instruction 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

     direction LR
%% DTCCCAISSD1V01 recursion level 0 with max 0
DTCCCAISSD1V01 *-- "0..1" SecuritiesQuantityDetailsSD1 : SecuritiesQuantityDetails
  

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

SecuritiesQuantityDetails building block

Information to be extended as supplementary data to security quantity details. Provides information about securities quantity linked to a corporate action option. Provides information about securities quantity linked to a corporate action option. For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCAISSD1V01 implementation follows a specific implementaiton pattern. First of all, DTCCCAISSD1V01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCAISSD1V01Document implements IOuterDocument. Because DTCCCAISSD1V01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCAISSD1V01.

    class IOuterRecord
    DTCCCAISSD1V01 --|> IOuterRecord : Implements
    DTCCCAISSD1V01Document --|> IOuterDocument~DTCCCAISSD1V01~ : Implements
    class IOuterDocument~DTCCCAISSD1V01~ {
        DTCCCAISSD1V01 Message
     }
  

Document wrapper for serialization

The only real purpose DTCCCAISSD1V01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.030.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCAISSD1V01.ToDocument() method. The returned DTCCCAISSD1V01Document 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.030.001.01">
    <DTCCCAISSD1>
        <SctiesQtyDtls>
            <!-- SecuritiesQuantityDetails inner content -->
        </SctiesQtyDtls>
    </DTCCCAISSD1>
</Document>
