Media Overlays Validation

Notes on the implementation of Media Overlays validation:

  • The OverlayChecker#validate() method currently only verifies the publication's SMIL file(s), it should also verify the OPF metadata specific to Media Overlays (total duration == sum of individual spine items duration, CSS "active" class checks?).
  • The OverlayHandler class doesn't verify durations (clip-begin / end pairs), it should also cross-check with the corresponding OPF metadata.
  • The OverlayCheckerFactory doesn't need to do anything else.
