The AVVideoCompositionValidationHandling protocol declares methods that you can implement in the delegate of an AVVideoComposition object to indicate whether validation of a video composition should continue after specific errors have been found.

You might chose to stop validation after particular errors have been found so as to avoid unnecessary subsequent processing following an eror from which there is no suitable recovery.
