• EDI transactions are surrounded by 6 envelope
  segments. These segments contain important
  routing information, such as ids, version, and
  transaction type.
• ISA/IEA Interchange Envelope
• Contains an entire transmission
• GS/GE Group Envelope
• Contains one group of similar transactions
  (e.g., multiple purchase orders)
• ST/SE Transaction Set Envelope
• Contains data that describes one single
  transaction (e.g., one pay order)
