-- # 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.
