What am i dooing wrong?? (setfacl problem)

["Jeffrey D. Means" <meaje@picotech.net>]

[root@trouble www]# setfacl --version
setfacl 2.0.4
[root@trouble www]# mount
/dev/sda1 on / type xfs (rw)
none on /proc type proc (rw)
/dev/hda1 on /boot type xfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/hda2 on /home type xfs (rw)
none on /dev/shm type tmpfs (rw)
/dev/hdb1 on /samba type xfs (rw)
/dev/sdb2 on /tmp type xfs (rw)
[root@trouble www]# setfacl -m u:meaje:rwx,mask:rwx html
setfacl: html: Operation not supported
[root@trouble www]#

Why is this operation not supported?  I am in a directory under /home
which is an XFS filesystem.  I really want to apply the default
permissions to this directory but will be happy if this user can write
to it.  I installed and formatted these drives with the 1.0.2 install
iso cdrom image file off your website, the rest of the install is basic
RedHat except I have recompiled a kernel and xfs commands using the cvs
tree on 3/14/02.
