Good points, I've removed the MediaList interface and amended the text
to read:
        If the user selects files of whose MIME types match image/*,
        sound/*, or video/* (on the filesystem or via a successful media
        capture), the relevant files in the files attribute [HTML5] must
        implement the MediaFile interface.

So, you're suggesting an asynchronous MediaFile.getFormatData() rather
than the MediaFile.format attribute? I can see the value of not loading
up data into memory ever time, but this will make access to these data
rather more painful for developers; that may be an acceptable price to
