I found that I was confused with the name "loext:text-direction", and
connected it to writing-mode.
In different context direction may mean writing direction in Bidi text, as
in [1].
Is that new  "loext:text-direction" attribute only intended to rotate text
for RL_TB writing mode?
( wordArtVert and wordArtVertRtl should also be excluded in that case? )
