Since the Brief description mentions NNPA, shouldn't the Public
Description expand on this "NNPA" acronym?, something like:
Oops, can't expand on that since there isn't a link to that SA22-7832-13

Googling for it...
https://www-40.ibm.com/servers/resourcelink/svc03100.nsf/pages/zResourceLinkUrl?OpenDocument&url=http://www.ibm.com/servers/resourcelink/lib03010.nsf/0/B9DE5F05A9D57819852571C500428F9A/$file/SA22-7832-13.pdf
Ok, requires registration.
I wonder what is the value of these descriptions then :-\
I miss Ingo jumping into these discussions :-)
