//! [`PersonalDataRecordId`] — names a record of personal data held outside a
//! passport.

/// `PersonalDataPort` in the ports module.

/// Opaque, and minted by whoever holds the record. It goes into a signed,
/// retention-locked passport, where it outlives the record it names, so it must
/// carry nothing derived from the data or from the person: once the record is
/// erased, the identifier left in the passport must say nothing about anyone.
