Please explain what does not make sense, because that is exactly what
I want to do.

I want to define the class ONLY if the file is edited.  But which
class I want do define depends on which modification is done, this, I
think, could be implemented with using multiple 'editfiles' instead of
using 'BeginGroup....', but in this example I didn't used that.
