That is a transformation, not a writing direction. With the exception of
the Phaistos disk and Mayan, all writing systems are either horizontal
or vertical; graphical effects can make them appear at other angles
(text on a path, radial text, etc) but the actual writing direction is
one or the other.

Mixed orientation is typically at the block level.

I tend to agree, we should look at what XSL does here.
