DTCCCARESD1V02

supl.025.001.02

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

     direction LR
%% DTCCCARESD1V02 recursion level 0 with max 0
DTCCCARESD1V02 *-- "0..1" CorporateActionGeneralInformationSD35 : CorporateActionGeneralInformation

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 notification general information. Provides additional information regarding corporate action general information. For comparison, see the ISO20022 official specification

%% CorporateActionGeneralInformationSD35 recursion level 0 with max 1
class CorporateActionGeneralInformationSD35{
    PlaceAndName IsoMax350Text
    EventGroup EventGroup3Code
    EventType ExtendedEventType6Code
    SubEventType DTCCSubEventType6Code
}

CorporateActionGeneralInformationSD35 members

Member name	Description	Data Type / Multiplicity
PlaceAndName	Xpath to the element that is being extended.	IsoMax350Text - Optional 0..1
EventGroup	DTC processing domain/ category for event types.	EventGroup3Code - Optional 0..1
EventType	DTCC (The Depository Trust and Clearing Corporation) native corporate action event type name. Used in place for the events that cannot be classified by ISO code and mapped to OTHR or when two or more distinct events (in DTCC model) use same ISO code and there are no additional data elements that distinguish those two or more events.	ExtendedEventType6Code - Optional 0..1
SubEventType	DTCC (The Depository Trust and Clearing Corporation) native corporate action sub event type name further defines the event type.	DTCCSubEventType6Code - Optional 0..1

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCARESD1V02 implementation follows a specific implementaiton pattern. First of all, DTCCCARESD1V02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCARESD1V02Document implements IOuterDocument. Because DTCCCARESD1V02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCARESD1V02.

    class IOuterRecord
    DTCCCARESD1V02 --|> IOuterRecord : Implements
    DTCCCARESD1V02Document --|> IOuterDocument~DTCCCARESD1V02~ : Implements
    class IOuterDocument~DTCCCARESD1V02~ {
        DTCCCARESD1V02 Message
     }

Document wrapper for serialization

The only real purpose DTCCCARESD1V02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.025.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCARESD1V02.ToDocument() method. The returned DTCCCARESD1V02Document 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.025.001.02">
    <DTCCCARESD1>
        <CorpActnGnlInf>
            <!-- CorporateActionGeneralInformation inner content -->
        </CorpActnGnlInf>
    </DTCCCARESD1>
</Document>
