The document format is a gl issue, but I think we want clear understanding of the preferred document format if we want SMIL players to be able to reposition and control formatting of captioning information. I assume the author could hard code the captioning information into the video stream, which would not allow it to be repositioned or reformatted. Is this true? Or do I not understand the SMIL format?
