Re: Requirements for attachments^H^H^H transport optimisation

A better place for this discussion might be the XML Binary 
Characterisation WG;
   http://www.w3.org/XML/Binary/

That's not to say that these aren't important considerations for MTOM, 
but the XBCWG was formed specifically to talk about them.
