Original Title was: Introduce "Attribute Accumulation" parameters group into SpatialFilter and SpatialRelator
In FME 2015, a common parameters group called "Attribute Accumulation" has been introduced into some transformers, which allows users to control how to resolve conflict between attribute names. e.g. Clipper, FeatureMerger, NeighborFinder.
Like that, I think that the SpatialFilter and SpatialRelator may also have the "Attribute Accumulation" parameters group.
