+-- # 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.
