          A Point is 1/72 of an inch. I would say that is kind of a
universally accepted fact. Whether microsoft interprets it differently is a
matter of conjecture.

Then what you have should work.  Because you do not have margin="0pt"
the formatter is supposed to keep the text in alignment with adjacent
unbordered text and draw the border outside the parent area limits.

No comment ... I do not know the answer.

Correct ... but I counsel my students to use before/after/start/end
to be portable.

>What about space-* vs padding-*?

I'm not sure what is confusing about my answer above:  they are
different concepts.  There are different rectangles in play in XSL-FO
and I told you above that space-* is outside of the outside edge of
the border and padding-* is inside the inside edge of the border.

I don't know how else to describe it to you.

Then don't use margin-left="0pt" and a conforming XSL-FO engine will
push the border out leaving the text in alignment with adjacent
unbordered blocks.

I hope this helps.
