This is inconsistent and wrong. The 1996 Duden says (R4): "Bei der
Abschnittsgliederung *mit Ziffern und Buchstaben* steht der Punkt nach
römischen und arabischen Zahlen und nach Großbuchstaben." i.e. the dot
has to be after numbers *and* letters, if there is an appendix. I cannot
find this rule in the 2004 Duden (23. Auflage), though.
I have 2006 Duden (24. Auflage) and can't find it either. I don't know
why the'd bulid this option in that package. Very strange.
I found some discussion at:
Help with the (non-existent) points in the numbering of parts and appendices

When I will this text finshed I gonna contact the author of koma script
for clarification.
Strange that no one else wondered about this. Especially the issue
reported for figures and tables is wired:

What can I do to get the above described formatting?
I don't know if it is possible. You can leave the dot or have it, but
having it with letters and leaving it with numbers is not desired.
Yes, I'll use "pointlessnumbers".
Thanks for answering, through!
