The ReversalResponse message is sent by an issuer or an agent to an acquirer in response to a ReversalInitiation 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 ReversalResponseV02 implementation follows a specific implementaiton pattern. First of all, ReversalResponseV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, ReversalResponseV02Document implements IOuterDocument. Because ReversalResponseV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type ReversalResponseV02.

ReversalResponseV02 --|> IOuterRecord : Implements
ReversalResponseV02Document --|> IOuterDocument~ReversalResponseV02~ : Implements
class IOuterDocument~ReversalResponseV02~ {
ReversalResponseV02 Message
}
Document wrapper for serialization
The only real purpose ReversalResponseV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:cain.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 ReversalResponseV02.ToDocument() method. The returned ReversalResponseV02Document value will serialize correctly according to ISO 20022 standards.
