The AcceptorAuthorisationResponse message is sent by the acquirer (or its agent) to an acceptor (or its agent), to return the result of the validation made by issuer about the payment transaction.
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 AcceptorAuthorisationResponseV06 implementation follows a specific implementaiton pattern. First of all, AcceptorAuthorisationResponseV06 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorAuthorisationResponseV06Document implements IOuterDocument. Because AcceptorAuthorisationResponseV06 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorAuthorisationResponseV06.

AcceptorAuthorisationResponseV06Document --|> IOuterDocument~AcceptorAuthorisationResponseV06~ : Implements
class IOuterDocument~AcceptorAuthorisationResponseV06~ {
AcceptorAuthorisationResponseV06 Message
}
Document wrapper for serialization
The only real purpose AcceptorAuthorisationResponseV06Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.002.001.06’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorAuthorisationResponseV06.ToDocument() method. The returned AcceptorAuthorisationResponseV06Document value will serialize correctly according to ISO 20022 standards.
