Try to see it like this: A tag on a ring describes a property that belongs
to the whole inside of the ring. So a tag on an "inner" ring has nothing to
do with the relation (that's the meaning of "inner" - an area that does
*not* belong to the area described by the relation).
For "outer" rings it is similar: If you tag a property to the relation you
explicitely say: this property does not belong to the holes (marked with
"role=inner). If you tag the outer ring you don't make clear what you mean.
