The ATMWithdrawalRequest message is sent by an ATM to an acquirer or its agent to request the approval of a withdrawal transaction at an ATM.
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 ATMWithdrawalRequestV02 implementation follows a specific implementaiton pattern. First of all, ATMWithdrawalRequestV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, ATMWithdrawalRequestV02Document implements IOuterDocument. Because ATMWithdrawalRequestV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type ATMWithdrawalRequestV02.

ATMWithdrawalRequestV02 --|> IOuterRecord : Implements
ATMWithdrawalRequestV02Document --|> IOuterDocument~ATMWithdrawalRequestV02~ : Implements
class IOuterDocument~ATMWithdrawalRequestV02~ {
ATMWithdrawalRequestV02 Message
}
Document wrapper for serialization
The only real purpose ATMWithdrawalRequestV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:catp.001.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using ATMWithdrawalRequestV02.ToDocument() method. The returned ATMWithdrawalRequestV02Document value will serialize correctly according to ISO 20022 standards.
