I am using FME to fill in some small holes within polygons. I have used DonutHoleExtractor to split these out, however I have found the output via the HOLE port also brings existing 'filled' holes (valid polys that have an outershell).
How can I differentiate these??

If you're trying to fill the holes with the same attributes of the outershell, then you shouldn't need to use the HOLE port. The transformer description shows a picture of the output. The outershell is essentially a filled polygon.
Your input data may actually have valid polygons which are coincident with the holes.
Am I answering your question? Or am I missing something?
