I am not sure I understand your tagging proposal correctly, but by posing 
an example you might be able to make this clearer.

I live near a street called the Bacchuslaan. On one side of the street 
it's Borgerhout and on the other it is Berchem. The border runs through 
the street and does not cross it. So,

* I would add this way to 2 relations.

* The member belonging to the relation for Berchem would then be marked 
with role=left

* and the other relation forming the border of Borgerhout would then be 
modified by adding the street as member with role=right

Is this what you propose?
