     -- Identification of the mobile application that generated the barcode
     --   and filled in the data of its dynamic part.
     --
     -- The possible values are defined by the security provider
     --   (the security provider being UicBarcodeHeader.level2SignedData.level1Data.securityProviderNum/IA5)
     dynamicContentMobileAppId IA5String OPTIONAL,

     -- Moment of generation of the dynamic content, expressed in UTC
     dynamicContentTimeStamp TimeStampData OPTIONAL,

     -- Coordinates of the place where the dynamic content has been generated
     --   (same GeoCoordinateType type as in UicRailTicketData)
     dynamicContentGeoCoordinate GeoCoordinateType OPTIONAL,
  
     -- Response from the mobile to any data received from the terminal.
     --   The data received from the terminal may be a random number, or any other information.
	 --   The response may be the received data itself, possibly completed with other information
     --     (e.g. IMEI, mobile phone number, user identifier assigned by the phone-app...),
	 --     the whole being returned as is, or hashed, or modified in some way.
	 --
     -- The type used is a SEQUENCE OF ExtensionData
	 --   (the same ExtensionData type as in UicRailTicketData, as it is fully adapted),
	 --   in which extensionId identifies the content of extensionData.
	 --
	 -- Two types of value are possible for extensionId:
	 --   * predefined standardized values
	 --     (e.g. "=" if extensionData is exactly the data received from the terminal)
	 --     The list of predefined values is available on the UIC FCB User Group GitHub.
	 --   * "_" followed by any other value, defined by the security provider, in other cases.
	 --     (the security provider being UicBarcodeHeader.level2SignedData.level1Data.securityProviderNum/IA5)
     dynamicContentResponseToChallenge SEQUENCE OF ExtensionData OPTIONAL,
  
     -- Proprietary data defined bilaterally
	 --   (same ExtensionData type as in UicRailTicketData).
	 -- extensionId identifies the content of extensionData,
	 --   it shall be set to "_" + RICS + addon chosen by the issuer identified by its RICS code
