MediaStream Recording API question

Refer to https://dvcs.w3.org/hg/dap/raw-file/tip/media-stream-capture/MediaRecorder.html 2013/6/12 draft

1. From this statement: "it must raise a DOMError event, followed by a dataavailable event containing the Blob it has gathered, follwed by the stoprecording event."
Where is the stoprecording definition? Is onstop?
2. At stop method sec 4. Raise a done event, what is done event?
3. If the mediaStream status become stopped or finished, should the MediaRecorder stop encoding the raw data and raise a DOMError to notify UA? Also raise onstop event to UA？
4. What the expect behavior if user use this loop to retrieve encoded data

    var mr = new MediaRecorder(mediaStream)
    mr.start();
    mr.ondataavailable = function(e) 
                         {
                          //processing blob e  
                          mr.requestData();  
                        }
    mr.requestData();

If there is no encoded data now, should we fire a ondataavailable event to UA with blob size = 0 immediately ? Or delay to fire the ondataavailable event until MediaRecorder get encoded data?
5. What's MdiaSteamEvent, on part 7, Event name : resume; Interface MediaSteamEvent
