This seems open to interpretation.  If you define "SOAP response" as "a
SOAP envelope", then it's not immediately obvious how this is so.  If
you define SOAP response as "a SOAP envelope or something else", then
this is clearly true, but it's not clear what value it adds.

The distinction being made is between HTTP responses that contain SOAP
envelopes and those that don't.  Both are clearly possible on the wire. 
Whether that distinction is semantically relevant other than on the wire
is a separate issue.  I would prefer to talk about that issue rather
than what a "SOAP response" is or isn't, though of course I realize that
agreeing on a common definition of "SOAP response" ought to aid that
discussion.
