- DASH IOP requires AdaptationSets with video Representations to have:
@maxWidth (or @width if all the Representations have the same width).
@maxHeight (or @height if all the Representations have the same width).
@maxFrameRate (or @frameRate if all the Representations have the same
frame rate).

Additionally, for XML schema correctness, convert ISO-639-2 language
tags (three-letter codes) to ISO-639-1 tags (two-letter codes) when
possible. This follows BCP-47, which says to always use the shortest
language tag when there are multiple possibilities.
