Registries

Public code lists and profile references.

Registries help implementations stay consistent. Most visitors do not need them for a basic verification, but implementers and evaluators often do.

Why registries exist

  • Keep profile and code references stable.
  • Make reason codes easier to interpret consistently.
  • Support conformance and implementation work.
