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 SaleToPOIServiceRequestV04 implementation follows a specific implementaiton pattern. First of all, SaleToPOIServiceRequestV04 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, SaleToPOIServiceRequestV04Document implements IOuterDocument. Because SaleToPOIServiceRequestV04 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type SaleToPOIServiceRequestV04.
classDiagram
class IOuterRecord
SaleToPOIServiceRequestV04 --|> IOuterRecord : Implements
SaleToPOIServiceRequestV04Document --|> IOuterDocument~SaleToPOIServiceRequestV04~ : Implements
class IOuterDocument~SaleToPOIServiceRequestV04~ {
SaleToPOIServiceRequestV04 Message
}
Document wrapper for serialization
The only real purpose SaleToPOIServiceRequestV04Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:casp.001.001.04’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using SaleToPOIServiceRequestV04.ToDocument() method. The returned SaleToPOIServiceRequestV04Document value will serialize correctly according to ISO 20022 standards.
