[talk-ph] no uturn on a dual-carriageway, how?

[maning sambale]

This spot:
http://www.openstreetmap.org/?mlat=14.589184&mlon=121.071306&zoom=18&layers=B000FTF

allows you to take left and right turns but not u-turns

According to this document,
http://wiki.openstreetmap.org/wiki/Turn_restrictions

relation turn restrictions should have 3 members (from, to, via)  But
this spot should have 5 members (3 ways and 2 via nodes).

What is the correct relation "membership" for this case?
