A product group decides which schema a passport is validated against and which rules run over it. Each page below is generated from the manifest the software itself reads, so a page cannot claim a schema version the code does not serve.

Modelled is not the same as mandated. Most of these have no delegated act yet. Modelling one early means the schema, the rules and the disclosure split exist to be argued with now, rather than written in a hurry once a date is fixed — and every page says plainly where its fields are a best reading rather than a requirement.
