The BusinessMessageEnvelope is a technical message container used to bundle a business application header with a message definition, typically to support processing or transport. It may contain and define additional data elements that apply to the message instance container.
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
classDiagram direction LR %% BusinessMessageEnvelopeV01 recursion level 0 with max 0 BusinessMessageEnvelopeV01 *-- "0..1" IsoLaxPayload : Header BusinessMessageEnvelopeV01 *-- "1..1" IsoLaxPayload : Document BusinessMessageEnvelopeV01 *-- "0..1" Reference22 : Reference BusinessMessageEnvelopeV01 *-- "0..1" SupplementaryData1 : SupplementaryData
Now, we will zero-in one-by-one on each of these building blocks.
Header building block
ISO 20022 Business Application Header instance. Rule: The external schema must be an official ISO 20022 Business Application Header. Specifies a data structure that allows to include any valid XML Structure (e.g. through an XML Schema). The property namespace is set to ‘any’. The processContents value is ’lax’ which according to the above specification and to Iso20022:2013 means: If the item has a uniquely determined declaration available, it must be ·valid· with respect to that definition, that is, ·validate· if you can, don’t worry if you can’t, i.e. it MAY be validated or not. For comparison, see the ISO20022 official specification

Document building block
ISO 20022 Message Definition instance. Rule: The external schema must be an official ISO 20022 Message Definition. Specifies a data structure that allows to include any valid XML Structure (e.g. through an XML Schema). The property namespace is set to ‘any’. The processContents value is ’lax’ which according to the above specification and to Iso20022:2013 means: If the item has a uniquely determined declaration available, it must be ·valid· with respect to that definition, that is, ·validate· if you can, don’t worry if you can’t, i.e. it MAY be validated or not. For comparison, see the ISO20022 official specification

Reference building block
Reference related to the delivery of the business message whilst in transit from sending to receiving business application. Reference of the business message envelope. For comparison, see the ISO20022 official specification

SupplementaryData building block
Additional information that cannot be captured in the structured fields and/or any other specific block. Additional information that can not be captured in the structured fields and/or any other specific block. For comparison, see the ISO20022 official specification

SupplementaryData1 members
Member name | Description | Data Type / Multiplicity |
---|---|---|
PlaceAndName | Unambiguous reference to the location where the supplementary data must be inserted in the message instance. In the case of XML, this is expressed by a valid XPath. | IsoMax350Text - Optional 0..1 |
Envelope | Technical element wrapping the supplementary data. | IsoSupplementaryDataEnvelope1 - Required 1..1 |
Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the BusinessMessageEnvelopeV01 implementation follows a specific implementaiton pattern. First of all, BusinessMessageEnvelopeV01 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, BusinessMessageEnvelopeV01Document implements IOuterDocument. Because BusinessMessageEnvelopeV01 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type BusinessMessageEnvelopeV01.
classDiagram class IOuterRecord BusinessMessageEnvelopeV01 --|> IOuterRecord : Implements BusinessMessageEnvelopeV01Document --|> IOuterDocument~BusinessMessageEnvelopeV01~ : Implements class IOuterDocument~BusinessMessageEnvelopeV01~ { BusinessMessageEnvelopeV01 Message }
Document wrapper for serialization
The only real purpose BusinessMessageEnvelopeV01Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:nvlp.001.001.01’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using BusinessMessageEnvelopeV01.ToDocument() method. The returned BusinessMessageEnvelopeV01Document value will serialize correctly according to ISO 20022 standards.
