What is ExtenderFunctionType.Unknown used for?

[Kai]

In the extensibility rule, there is a case choice of ExtenderFunctionType.Unknown. I am wondering in which situation we should use this? It would be great if we could have a few use cases with examples. Thank you

I am not sure if there are other situations where ExtenderFunctionType is Unknown, but when directly executing the extender in the editor the ExtenderFunctionType is Unknown. 

My use case for this was writing some hardcoded data values under the Unknown case for testing functionality during extender business rule development.

Thank you very much!
