Is there an expected/intended way to express an offset between a ruby
annotation box and its associated ruby base box in the block progression
dimension?

I see that Antenna House defines an '-ah-ruby-offset' property [1] for this
purpose.

The TTWG is trying to determine the best way to express this layout style
property in TTML that can map to CSS, a function which has been requested
[2][3] in order to support SMPTE ST 428-7 [4].
