Section 3.1 says:

It should say:

If all of the preconditions are true and the target representation
length is zero, the server SHOULD send a 200 (OK) response.


An empty representation is unsatisfiable according to section 2.1, but not unsatisfiable according to section 4.4 if the first-byte-pos is zero. An empty 200 response is the simplest solution to this contradiction, since it is a valid response anyway (if the server chooses to ignore the Range header), clients already handle it properly, it provides all necessary information to the client, and stating it explicitly can prevent subtle edge-case pitfalls in both the RFC and its implementations.
