As AS2 has grown in acceptance and maturity, its interest and abilities has spread beyond just secure EDI transfer. A draft for exchanging certificates over EDIINT has been submitted for review, and members of PIDX/CIDX are interested in sending multiple documents in an AS2 message through the use of multipart/related structure.
With this growth of features, what is the best way for implementations to convey their feature support? AS2-Version header has been used since compression was introduced, but this is very limited means of support communication. Within the DGI interoperability test, a vendor suggested the introduction of a Features header that could convey what the implementation supported (e.g. Compression, CEM, etc.) to assist trading partners in knowing the limits of their relationship.
What do the members of this work group consider of this idea or are their other solutions to this need?
