+-- # Please check this link to see if a more recent version of this file is available.

+-- # The type UicDynamicContentData defined below is at least intended to generate a data

+-- # that, once valued and encoded as PER unaligned [UPER],

+-- # is to be stored in UicBarcodeHeader.level2SignedData.level2Data.data, 

+-- # and identified as "FDC1" in UicBarcodeHeader.level2SignedData.level2Data.dataFormat.
