Locale Data from IBM

[Holly Lee <lee@mail.lib.sjtu.edu.cn>]

Hi, guys

I found IBM created their Locale Data for glibc-2.2.
See http://oss.software.ibm.com/developerworks/opensource/locale/ for
detail 
information.

My questions:
Is there anyone evaluated these locale data?
Is there any difference between them and Locales included in glibc-2.2
itself?

Best regards,
