Issue with a SHOULD NOT is that Content-MD5 may be present, and in that 
case we have a real interoperability issue. It is one of the few areas 
where we need to break compatibility (but as not that many servers are 
sending Content-MD5, and even less for Content-MD5 for 206 responses, it 
is quite unlikely that it will break implementations)
