This Amendment contains some changes to the main body and to Annex A of Recommendation T.434 to extend the binary file transfer format. The extension is to introduce two new attributes: store-and-forward and file-retrieval. Store‑and-forward attribute indicates information used by store-and-forward system. It contains characteristics of a document that is transferred, routing information and delivery information. File-and-retrieval attribute contains information for archiving, management and manipulation of documents.
