Redundant identifiers

Under documents, why can passport be generically used for all countries, but de and jp require so many document types?

Especially since there are issuer details as part of the schema which denote country.

Perhaps some could be merged / removed?

Also the naming is inconsistent: driving_permit / jp_drivers_license
