I worked with this interchange format for a few years developing customs brokerage and logistics software. There’s like 50 different versions of the language when you count up official EDIFACT revisions and some poorly implemented versions of it per countries customs system. At one point there was even a XML version but I don’t think it caught on. I once unintentionally broke a particular countries customs system by sending the maximum number of messages in a single interchange envelope. System was out for 3 days whilst shipping containers couldn’t be moved out of their major seaport. Still amazed they had Christmas that year!
