What part of the spec specifies this? I just did a search and there
aren't any instances of the strings "right-to-left" or "left-to-right"
on the spec. I'm not entirely sure what you mean by RTL-embedding
unicode. I understand that unicode alone is not supposed to tell you teh
writing direction. Not long ago I and others got an email from Jonathan
Ben Avraham, from the Israel delegation at ISO. In brief, he said that
there needs to be an attribute for writing direction and that character
encoding is no good. I found a copy of his email:

Jonathan's email says that character encoding is not enough (I don't
know if what you described is character encoding). I can't really say if
the present situation is enough, because I can't find the portions of
the spec that you are referring to.
I notice that when ODF was approved at ISO a lot of comments were about
insufficient Bidi support. Do you think this is because the ISO members
didn't realize which parts of the spec gave proper bidi support?
Best,
Daniel.
