This may have been covered elsewhere and I missed it, but is there
a concrete definition of "big chunk" that would trigger the media-type
change? (Presumably, if some part of the SOAP payload is encrypted
(a credit card field in a shipping invoice, say), you wouldn't 
advocate that the media-type be changed). Is it based on encrypting
all the SOAP headers, contents of SOAP headers, envelope, etc.?
