A double bar in CSS syntax is "one or more of them must occur, in any
order"[1], so I think Masayuki's syntax "[auto|under] || [left|right]" should
give you what you proposed.

Also there's a text saying "If left or right is specified alone, under is
also implied", not explicitly written but I think Masayuki implied to
change this too by the syntax change.

Even after the change to the syntax was made?
