The spec currently requires in the coded frame processing algorithm that
implementation detect dependencies between frames so that removal of a frame
removes all dependent frames. 

This is a strong requirement on implementations which is impossible to fulfill
(at least with current media formats) without decoding the frames (codec
specific parsing). 

The requirement should be removed. Applications should make sure that they
append frames that don't depend on non appended frames or that overlapped
frames are not needed by non-overlapped frames.
