I agree with all of the above.

Hmm, I'm still not sure why you don't think it's a good idea for an
Author to do that.  Let me give an example.  Let's consider the case
where in an RTL page, I want to show a European address (which should
be written in LTR) on a map as a static image displayed using an img
tag.  In order to support the users who have turned image display off,
for example, I may put the address as the alternate text for the
image.  But the address will be displayed in RTL mode, which is not
what I intend.  I don't see what's different about this use case
compared to the one you suggested for supporting @titledir for @title.

No, but I also don't see why we should specify that there should not
be a CSS equivalent, provided that the CSS WG can come up with a good
reason why there needs to be one.
