No, no, you're right, the important point I wanted you to read was
INHERITANCE. 

<foo dir="ltr">
<bar> <!-- Has dir="ltr", from inheritance -->
Bla bla
</bar>
Bla again
</foo>

> Yes, my question was why the draft needs dir="" at all,

Because, as I said, otherwise, you could not express the fact that the
direction of the text in the <bar> element above is "Not
Known". Without dir="", you could not "cancel" the directionality of
<foo> in its nested elements.
