== Styling using tts:direction: should there be an auto value? ==
https://w3c.github.io/ttml2/spec/ttml2.html#style-attribute-direction

TTML does define a `direction` attribute for `p` and `span` elements 
for use in controlling text direction (bidi). The values provided are 
`ltr` and `rtl`. There is not `auto`. Should there be?
