The document is not static; it evolves continuously. The custodian for APP-11 on behalf of NATO is the . In this capacity, the Royal Navy manages the entire lifecycle of the catalogue, from identifying operational needs to final publication. It also represents NATO's interests in the Information Exchange Requirements Harmonisation (IERH) Working Group , the body responsible for its content.

: Certain unclassified, legacy editions of APP-11 or related ADatP-3 guidelines are occasionally hosted on academic or public defense repositories for educational purposes. However, developers should always ensure they are working with the active version required by their specific project guidelines.
Every message must strictly adhere to the allowed vocabulary (allowed words or acronyms) and character lengths defined in the APP-11 specification. If a field expects a date-time group (DTG), entering standard text will cause the automated system to reject the message. The Evolution of APP-11: From Text to XML
