I still don't see the need for this feature from this example.
First, in ebXML messaging, the message are typically *not* large
(i.e. much smaller than 100 MB). Furthermore, the typical processing
of such a message would be to pass it directly to the XML parser,
no need for the functionality under discussion.

If that was the case, wouldn't the existing Python web service
libraries already include such a functionality?
