Ok.  Then, based on what Murata-san says in
http://lists.w3.org/Archives/Public/www-style/2010May/0668.html
I am convinced that your proposal does not solve the problem.
Specifically, style sheets must cope with _on the fly user override_ of
writing direction; thus any approach depending on document annotations
cannot do the right thing in all cases.  We need a way for style sheets
to control formatting based on the way individual runs of text are
actually being drawn, regardless of why they are being drawn that way.

The HTML authoring guidelines are moot for the same reason.

This would make the first-line of a paragraph be indented from the
_left_ margin if it is left-to-right text, and from the _right_ margin
if it is right-to-left text.  In practice of course one would use
text-indent to get that effect; it is only an example.
