Solaris 11.2 extended attribute change

I have a file that shows up as having extended file permissions.

ls -V /usr/share/X11/app-defaults/XScreenSaver
rwx------   1 root     root          53 Dec  2 21:52 /usr/share/X11/appdefaults/XScreenSaver
          owner@:rwxp--aARWcCos:-------:allow
          group@:------a-R-c--s:-------:allow
          everyone@:------a-R-c--s:-------:allow

How do I remove extended attributes?

Thanks Lee
