Hi, I'm new to SOAP and have spent numerous hours trying to find an answer to the following fundamental issue. I hope somebody is kind enough to answer me on this one.

What is it about SOAP that makes this necessary? Are there examples where a SOAP engine starts sending a SOAP message even before all the data to be included exists, for example when the data is dynamically generated? Similarly, are there examples where a SOAP engine starts sending the SOAP message without buffering the whole message, say when a 1000 Gb picture of MIME type "image/jpeg&q   More>>

I think there's some kind of "attachment" thing, maybe a proposed extension to the standards? for such large amounts of data to be transmitted apart from the main SOAP message, and let the main message describe/refer to the other stuff?
