No, turn restrictions are supposed to be modelled through the use of
relations, however this is not yet formalised properly, see:

http://wiki.openstreetmap.org/index.php/Relations/Proposed/Turn_Restrictions

The reason for this is that there may be number of turn restrictions
at one node, depending on where you come from and where you want to
go, so the tags on the node would be overstretched to contain all
that.
