I can see what you are getting at, but the unexpected results crop
up because of the side effects that setting 'direction' has on other
CSS properties, and not so much on the bidirectionality of the text.
This will also be an issue primarily only for form elements where
the author cannot know what text will be displayed by the element.

I don't know what to think of this.  At the very least, a list of the
CSS properties that base default behavior on the value of 'direction'
should be compiled so that side effects from adding a new value for
'direction' can be evaluated before going ahead with the idea.
