The DTCCCACNSD1 message extends ISO corporate action cancellation advise (CACN) 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

| SecurityOfInterestMatchingSecurity | Security identifier that is used to match the customer’s SOI (Security of Interest) to the GCA VS Security Cross Reference. | SecurityIdentification15 - Optional 0..1 |
GeneralInformationExtension building block

| 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 are marked as OTHR. Can be used in combination with DTCC sub event type (when provided) to identify the event. For an example: a distribution based on recapitalisation event will be presented as event type: OTHR in standard message. DTCC native event type would be Distribution (DIST) and DTCC sub event type would be Recapitalisation. | ExtendedEventType1Code - Optional 0..1 |
| SubEventType | DTCC (The Depository Trust and Clearing Corporation) corporate action sub event type name further defines the event type. For an example: a cash dividend event eligible for dividend reinvestment at DTC election will be noted as event type: Cash Dividend (DVCA) and DTCC sub event type: DRIP( DTC only). | DTCCSubEventType1Code - Optional 0..1 |
EventsLinkageExtension building block

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the DTCCCACNSD1V02 implementation follows a specific implementaiton pattern. First of all, DTCCCACNSD1V02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCACNSD1V02Document implements IOuterDocument. Because DTCCCACNSD1V02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCACNSD1V02.
classDiagram
class IOuterRecord
DTCCCACNSD1V02 --|> IOuterRecord : Implements
DTCCCACNSD1V02Document --|> IOuterDocument~DTCCCACNSD1V02~ : Implements
class IOuterDocument~DTCCCACNSD1V02~ {
DTCCCACNSD1V02 Message
}
Document wrapper for serialization
The only real purpose DTCCCACNSD1V02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.006.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCACNSD1V02.ToDocument() method. The returned DTCCCACNSD1V02Document value will serialize correctly according to ISO 20022 standards.
