Oh, I'm not bookmarking such kind of content usually. I guess in any case a system that check the type of content (html/image/sound/video) will be needed to select the storage format, so the annotation may then also be adapted to the content type. In any case a way to manually add tag would exist so it's feasible to add such content.
