[css-writing-modes-3] line-under and line-over of text with 'text-orientation: upright'

Elika, Koji,

Where are line-under and line-over sides when text has its 
'text-orientation' set to 'upright'?

§7.5 Line-Relative Mappings
http://dev.w3.org/csswg/css-writing-modes-3/#line-mappings

"
For the text-decoration property, the underline is drawn on the under 
side of the text; the overline is drawn on the over side of the text.
"

does *not* provide such information ... which I think it should.

§6.3 Line-relative Directions
http://dev.w3.org/csswg/css-writing-modes-3/#under
http://dev.w3.org/csswg/css-writing-modes-3/#over
does *not* provide such information either.


After careful reading,
§6.4 Abstract-to-Physical Mappings
http://dev.w3.org/csswg/css-writing-modes-3/#logical-to-physical
provides such info but, even there, you have to understand that "*right" 
means upright too.

So, I suggest/propose to add/insert a sentence in section 7.5 indicating 
that line-under (line-over) for text with 'text-orientation' set to 
'upright' is at the physical lefthand (righthand) side of text.
