[Routing] Question about turnrestrictions

[Gubler, Ruediger]

Hello,

I have a question about the below turn restriction definition

<osm version="0.6" generator="OpenStreetMap server">
  <relation id="339483" 
   visible="true" 
   timestamp="2012-06-29T07:37:40Z" 
   version="4" 
   changeset="12053445" 
   user="Drachentoeter" 
   uid="63726">
    <member type="node" ref="82520384" role="via"/>
    <member type="way" ref="49025950" role="to"/>
    <member type="way" ref="28191636" role="from"/>
    <member type="way" ref="169412714" role="from"/>
    <member type="way" ref="169412708" role="from"/>
    <member type="way" ref="169412713" role="from"/>
    <tag k="restriction" v="no_left_turn"/>
    <tag k="type" v="restriction"/>
  </relation>
</osm>

According to the wiki (http://wiki.openstreetmap.org/wiki/Turn_Restriction) multiple from roles are only allowed at 
restriction=no_entry or restriction=no_exit elements. 

Is the above definition correct and the wiki is wrong or must the relation be divided into 4 parts?


Yours Rüdiger
