DTCCCASTSD1V02

supl.031.001.02

The DTCCCASTSD1 message extends ISO Corporate Action Instruction Statement Report 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

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCASTSD1V02 implementation follows a specific implementaiton pattern. First of all, DTCCCASTSD1V02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCASTSD1V02Document implements IOuterDocument. Because DTCCCASTSD1V02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCASTSD1V02.

classDiagram
    class IOuterRecord
    DTCCCASTSD1V02 --|> IOuterRecord : Implements
    DTCCCASTSD1V02Document --|> IOuterDocument~DTCCCASTSD1V02~ : Implements
    class IOuterDocument~DTCCCASTSD1V02~ {
        DTCCCASTSD1V02 Message
     }
  

Document wrapper for serialization

The only real purpose DTCCCASTSD1V02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.031.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCASTSD1V02.ToDocument() method. The returned DTCCCASTSD1V02Document 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.
