--- # Naming and encoding conventions
--- #
--- # Elements included as String and as Numeric values:
--- # Some elements are included in different formats to reduce the data size.
--- # These elements must be included only once.
--- # These elements are named with the same name and appendix
--- # Num (numeric values)
--- # IA5 (String values according to ASN IA5String (7Bit))
--- #
--- # RICS codes must be used to encode companies (issuer, product owner, ...) where available
--- # other codes are possible based on bilateral agreements
--- # the format is kept more flexible to cover upcoming extensions of the RICS code by ERA
--- #
--- #
--- # - A bar code which is only static (printed on a paper), and for which the security is in the system, doesn’t need any of these elements.
--- # - A bar code which is only static, and includes its own security, needs:
--- # level1Signature
--- # level1KeyAlg if the associated key does not include the complete certificate in keys.xml but only the public key
--- # (but level1SigningAlg is not necessary as it is in keys.xml)
--- # - A dynamic bar code including static and dynamic signatures needs:
--- # The same elements as a static bar code above,
--- # level2SigningAlg, level2keyAlg, level2PublicKey, and level2Signature.
