Remove one instance of "If the service has returned content in response to a request including a Prefer header with a value of return-content, it MAY include a Preference-Applied response header with a value of return- no-content." from section 8.5.2 The Preference-Applied Header. The second paragraph was intended to describe the no content case, and has been updated (as part of applying OData-110 for the new preference values) to: If the service has returned content in response to a request including a Prefer header with a value of return=representation, it MAY include a Preference-Applied response header with a value of return=representation. If the service has returned no content in response to a request including a Prefer header with a value of return=minimal, it MAY include a Preference-Applied response header with a value of return=minimal.
