Usage Notes

When attributes are merged between features, existing attributes are not replaced. Therefore if the polygons being overlaid have attributes with the same name, then the values will not be transferred from one to the other. You can work around this by renaming (AttributeRenamer), prefixing (AttributeExpressionRenamer), or removing (AttributeRemover) attributes to avoid name collisions.

Aggregates are not supported by this transformer.
