Filename in AS2 messages

["Dmitry Dolinsky" <dmitry.dolinsky@xxxxxxxxxxxxxx>]

I'd like to clarify how the filenames are expected to be communicated in 
AS2. Since AS2 data is represented by MIME body, the implication is that 
Content-Disposition header can be used for that purpose.

Is this a correct assumption?

If so, it would be great if AS2 spec made an explicit reference to RFC-2183 
(update of rfc1806) "Communicating Presentation Information in Internet 
Messages: The Content-Disposition Header Field"  with respect to AS2 
filename. I've noticed that the header is included in the samples that 
accompany the specification but making it explicit would improve 
interoperability.

Also, as a practical question, do current AS2 implementation include 
Content-Disposition header with filename parameter when sending and look 
for it when receiving as far as people know?

Thank you.
