Outside the cues:
  nothing — SRT stores cues and nothing else
  except 1 cue that had a comment line above it — that line stays attached to its cue

Reported while reading — repaired or skipped, never silently:
  1 × blocks with no readable timecode (they were skipped)
  1 × cues using SRT's non-standard X1/Y1 screen coordinate extensions
  1 × cues whose end time was not after their start time (they were given a 1ms duration)
