where are the pattern files?

Hi all,

I want to install openSUSE Leap 42.1 via pattern list.
But I can not find any pattern files in the installation repository (./suse/setup/descr/*.pat.gz)
In openSUSE 13.1 pattern files exist but since openSUSE 13.2 they seem to be gone.
In yast2 I can see patterns but what are their correct name to use them in a autoyast profile?
Where are all the patterns defined now?

Thanks in advance
Regards
Werner
