Introduction of a new MIC data set structure and format

SWIFT, as ISO 10383 Registration Authority, has enhanced the format and set of MIC data. The new format has been defined based on user requirements. The main purpose is to facilitate the automation of the file processing by the users.  MIC data users are requested to update their systems to the new format to benefit from the enriched content and from the automation capabilities.
