This would be very lightweight for all mappers, because it avoids clear lines which are confusing when they do not correspond with something observable." If you want to map something with a "fuzzy border", you should not map a non-fuzzy border and declare it "fuzzy" by adding tags. The data type should implicitly represent the fuzzyness. fuzzy is not the same as fuzzy. If you were to draw fuzzy borders with lines, I would expect at least 2 lines: one the is in and one that is out of the fuzzy object, the border would be the space in between, it's width (fuzzyness) could variate depending on the location. But the concept of using just nodes still seems more elegant and less invasive compared to this. Cheers, Martin
