No, it is not document-based.
I was already using setRequirtedFileType. But as you write, the 
extension is not shown automatically. Furthermore two things confuse: 
the first call to the change extension won't actually change it..., the 
second yes. Thus when just opening a file with a certain extension, 
trying to save it with another file type would try to add a second 
extension. Mac warns about that. But the new extension wasn't been shown.

SO my solution is to first remove the file extension of the file. That 
way either it gets automatically (not shown, but set correctly) or at a 
change it will be shown.

I think maybe not totally straight, but that is how it is set up on the 
mac. Now I hope my code works on GNUstep.
