-- #
-- # Naming and encoding conventions
-- #
-- # - A bar code which is only static (printed on a paper), and for which the security is in the system,
-- # does not 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.
-- #
-- # Changes to Version 1:
-- #
-- # - endOfValidity added in Level1Data
-- # - extension option added on all structures

DataType ::= SEQUENCE {
-- The value of 'dataFormat' describes how 'data' is encoded:
-- "FCBn" means that 'data' is the Canonical Unaligned PER encoding
-- of an ASN.1 element of type UicRailTicketData in major version n.
-- "FDCn" means that 'data' is the Canonical Unaligned PER encoding
-- of an ASN.1 element of type UicDynamicContentData in major version n.
-- "+" + [2-letters ISO 3166 country code] + [addon, chosen by the standardization body of that country]
-- means that 'data' is a content defined by the national standardization body,
-- identified as 'addon' by this body.
-- "_" + [4-digit RICS] + [addon, chosen by this company] means that 'data' is a proprietary
-- content of the company identified by the RICS code, identified as 'addon' by this company.
-- "*" + [addon] means that 'data' is a content specific to this barcode,
-- with no further information on who defined it, identified as 'addon' by its issuer.
-- Others values are reserved for future UIC use and shall not be used.
