The floating point values being used in X-Content-Duration can't
*exactly* express many durations, for example 130 frames at 30 fps.

Very close but not quite exact may be suitable for scaling a seek bar
in a browser, but it's not hard to imagine applications where the
*exact* duration is needed.

Should an opportunity be taken to support a rational number for
duration like is used for FPS?
