[ttml2] tts:writingMode example is not helpful

== tts:writingMode example is not helpful ==
https://w3c.github.io/ttml2/spec/ttml2.html#style-attribute-writingMode

The illustration of the `rltb` writing mode uses `unicodeBidi` 
override and `direction=rtl` to show some English text backwards. This
 isn't particularly helpful, since it isn't really an effect of 
writing mode and non-observant readers may not realize that the 
example has these features turned on in the example. They might 
therefore attribute the RTL results to the writing mode. I would 
instead suggest showing the text strongly right aligned, possibly in 
conjunction with an Arabic or Hebrew translation.
