Ok. I agree & understand.

I've a relational approach more than a spatial one.
To me, associations must be formalized through hard structured description
in a DB.
I'll have to adapt myself to that kind of data processing.

That situation is under the dispersed power plant configuration.
A relation will gather all features, including fenced perimeterS.
I know you would recommend to only add multiple perimeters to the relation
and get features inside from closed areas but it would introduce one more
case and increase proposal complexity.
According to what is recommended to do for choosing the best power plant
perimeter, it's only when the same operator owns multiple and distinct
perimeters for the same power plant infrastructure.
Instead we would have many different enclosed power plants with different
I've mapped a French hydro pumped-storage power plant as an example of
dispersed power plants.
There are actually 2 power plants, have a look to relations inside that

So we can drop all roles?
