Thanks for the review!

The spec didn't have these details, but it does now.

I don't understand what you're saying here.  The second and third
sentences appear to be completely unrelated to each other. (And the
third sentence is wrong - the list item's text-align has no effect on
the position of the marker.)

No.  I did have a 'hanging' value that would do this, but we dropped
it due to lack of use-cases.  Can you give examples of places where
people actually want this, or the behavior is clearly reasonably
attractive?  (This is roughly the current behavior of Firefox and
Opera with outside list markers.)

Is this actually required anymore?  Outside markers now pay attention
to the parent's direction without relying on text-align at all (it's
part of the details of "position:marker").  Was there any other
use-case for match-parent?

I don't have any problem with it.  Do inside list markers currently
affect bidi resolution in browsers?  I don't know enough about bidi to
really test this.
