I read the text as the MUST include only applying if the request is not
the result of an If-Range conditional request.

I don't read it as specifying which exact headers to include in an
If-Range based response when not respecting the SHOULD NOT, that case to
me is implementation defined. But that's my reading..

My point of bringing this up in the content of Content-MD5 is only to
show that sending Content-MD5 is NOT RECOMMENDED in most HTTP/1.1 206
responses, with the use of ETag and If-Range strongly recommended. This
kind of rules out Content-MD5 to be used as a message transport
validation method, even ignoring the other problems demonstrated
earlier.
