The AcceptorNonFinancialRequest message is sent by the POI to receive additional information from the Acquirer (or its agent).
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 AcceptorNonFinancialRequestV03 implementation follows a specific implementaiton pattern. First of all, AcceptorNonFinancialRequestV03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorNonFinancialRequestV03Document implements IOuterDocument. Because AcceptorNonFinancialRequestV03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorNonFinancialRequestV03.

class IOuterRecord
AcceptorNonFinancialRequestV03 --|> IOuterRecord : Implements
AcceptorNonFinancialRequestV03Document --|> IOuterDocument~AcceptorNonFinancialRequestV03~ : Implements
class IOuterDocument~AcceptorNonFinancialRequestV03~ {
AcceptorNonFinancialRequestV03 Message
}
Document wrapper for serialization
The only real purpose AcceptorNonFinancialRequestV03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.022.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorNonFinancialRequestV03.ToDocument() method. The returned AcceptorNonFinancialRequestV03Document value will serialize correctly according to ISO 20022 standards.
