I do not think that it is a case of defining multiple elements for one 
feature. If we think of a building, the shape of its outline is one 
feature, and the location of the main entrance is another. Knowledge of 
both is needed in order to find a route. You cannot normally walk over 
or through a building, and you can only enter it via an entrance.  
Therefore, it could be misleading to route to a POI in the middle of the 
building outline.

AFAICT, the source of the problem is the area-to-POI conversion, which 
does not take into account that a more accurate POI (at the boundary of 
the area) exists.
