AS3 (Applicability Statement 3) extends the procedures and payload packaging options of AS1 (Applicability Statement 1) and needs to be read in conjuction with AS1 and the referenced RFCs (Request for Comments) defining the MIME (Multipurpose Internet Mail Extensions) and cryptographic packaging that are used to obtain secure, authenticated, and acknowledged transport.  The "draft" AS1 (Applicability Statement 1) document describes how to exchange structured business data securely using SMTP (Simple Mail Transport Protocol) transport for EDI (Electronic Data Interchange).  AS3 extends the procedures and payload packaging options of AS1 in the following ways:

Basically, the following dozen permutations are possible in any given trading relationship:

  1. Sender sends un-encrypted data, does NOT request a receipt
  2. Sender sends un-encrypted data, requests an unsigned receipt.
    The receiver sends back the unsigned receipt
  3. Sender sends un-encrypted data, requests a signed receipt.
    The receiver sends back the signed receipt
  4. Sender sends encrypted data, does NOT request a receipt
  5. Sender sends encrypted data, requests an unsigned receipt.
    The receiver sends back the unsigned receipt
  6. Sender sends encrypted data, requests a signed receipt.
    The receiver sends back the signed receipt
  7. Sender sends signed data, does NOT request a signed or unsigned receipt
  8. Sender sends signed data, requests an unsigned receipt.
    Receiver sends back the unsigned receipt
  9. Sender sends signed data, requests a signed receipt.
    Receiver sends back the signed receipt
  10. Sender sends encrypted and signed data, does NOT request a signed or unsigned receipt
  11. Sender sends encrypted and signed data, requests an unsigned receipt.
    Receiver sends back the unsigned receipt
  12. Sender sends encrypted and signed data, requests a signed receipt.
    Receiver sends back the signed receipt

While you can choose any of the one-dozen possibilities, only the bolded example above offers the whole suite of security features for a "secure transmission loop".
