Personally I'm pretty un-opinionated on these details. If setting a range in the fragment results in the .currentTime spanning from 0 to length-of-range or from start-of-range to end-or-range seems only like a question of which API is the most author friendly. Script can always remove the range-fragment if it wants to use a .currentTime outside of the range. The only argument that I can think of either way is that it might be hard to create a decent UI for the situation when a range is specified, but .currentTime is set to outside that range using script. But again, I don't have much of an opinion. / Jonas
