Re: use cases for MTOM

Mark,

I mostly agree with you comments.

XMLP-UC-6 needs to be discussed further. One of the biggest advantages 
of using attachments is streaming. This can be positioned either as a 
usecase or a requirement.
For example, consider a header containing large binary data. If this 
binary data is contained in an attachment, then the sender (and 
receiver) can stream the data out (and in). This allows the receiver to 
start processing the SOAP message (for example looking at all the 
headers and checking for MU) before the binary data has been received 
(or sent by the sender).

Comments?
