After reading the draft, appears as setRequestHeader mustignore Content-MD5, User-Agent and From headers, as Content-MD5 can be only calculated after the send methodhas generated the data, and User-Agent and From are generally provided by the UA.
Content-MD5 is not set by most UAs, and so it's useful for the author to set it manually. While it may be difficult to calculate (esp. if the content is a DOMString), it's certainly possible.
Likewise, From is not normally set by UAs automatically, and it might be useful in some contexts.
I can easily see a case where a library or other XHR application might want to append something to the UA header.
