The ReconciliationInitiation message can be initiated by any party and received by any party (acquirer, agent or issuer).
Reconciliation is the exchange between two interchanging parties (Acquirer, Issuer or Agent) of totals and/or counts of messages within a specific session.
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 ReconciliationInitiationV03 implementation follows a specific implementaiton pattern. First of all, ReconciliationInitiationV03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, ReconciliationInitiationV03Document implements IOuterDocument. Because ReconciliationInitiationV03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type ReconciliationInitiationV03.

ReconciliationInitiationV03 --|> IOuterRecord : Implements
ReconciliationInitiationV03Document --|> IOuterDocument~ReconciliationInitiationV03~ : Implements
class IOuterDocument~ReconciliationInitiationV03~ {
ReconciliationInitiationV03 Message
}
Document wrapper for serialization
The only real purpose ReconciliationInitiationV03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caad.005.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using ReconciliationInitiationV03.ToDocument() method. The returned ReconciliationInitiationV03Document value will serialize correctly according to ISO 20022 standards.
