RE: [CSS3 Text] Thoughts on hanging-punctuation property

I think that the use of "edges" is implied in hanging punctuation. If "right" and "left" are necessary I would submit that the following would be appropriate.
 
  none | [start || end] | [left || right] | both
 
In the world of vertical text and multilingual documents I don't personally think that left and right should be added. 
 
The illustrations show normal hanging punctuation.

Yes, the edge of every line. I call that more than one. Sorry if my English
is a problem for my you. ;-)

Yes. I actually understood there was a internationalisation reason. But I
still thinks using left and right is better. It is basically the same
thing. But since CSS addresses almost every other direction using left and
right, I though it was best to use it here to. And as I said, it makes
things more simple.

If you look trough the two character blocks I proposed-try using
http://www.fileformat.info/info/unicode/block/index.htm-you will see that
it makes sense for almost every character. Except the U+2052 COMMERCIAL
MINUS SIGN and other glyphs that appear separated from other characters
using U+20 SPACE and other spacing characters.
