Context: Legacy answer to a cancellation/query compared with a structured resolution of investigation.
EVIDENCE AT ARM'S REACH
Use the official definitions for both sides of the translation and inspect the original teaching samples before implementing a mapping.
An XSD checks XML structure. A usage guideline adds profile rules, conditional fields, code restrictions, and business controls. XSD-valid does not mean scheme-compliant.
Choose the exact message definition in the official catalogue. The base XSD checks XML structure; it does not prove compliance with a scheme profile.
The annual MT standard and release information. Full field specifications may require an authenticated Swift account.
The network profile that restricts how ISO 20022 payment and reporting messages are used for cross-border traffic.
Adds the November 2026 validation and structured-address changes; implement against the final SR2026 usage guidelines.
Final usage guidelines are published through MyStandards; the public release page gives the implementation timeline.

Swift Standards MT (annual standards releases) ↗ — Swift
Full field-level specifications live in the Swift Knowledge Centre User Handbook behind a swift.com login. Coexistence for in-scope FI-to-FI payment instructions ended on 22 November 2025, but treatment differs by MT: some instructions are NAKed and selected messages can enter temporary, chargeable contingency conversion. Reporting, initiation, investigations and correspondence follow separate roadmaps.
ISO 20022 Catalogue of messages ↗ — ISO 20022 Registration Authority
Each message set is described by a Message Definition Report; earlier versions remain available in the ISO 20022 messages archive.

What this simplifies: Curated lifecycle-level mapping.
Used wherever diagrams, scenarios, figures, or example values are didactic constructions rather than sourced facts; every such use carries a simplifications disclosure. All people, companies, banks, and list entries in examples are fictional.
