different modes for symlinks?

Hi,

I'm wondering about different modes of symlinks on XFS filesystems:

# ll /usr/tmp /usr/src/linux
lrwxr-xr-x   1 root     root           19 Jul 10 00:36 /usr/src/linux ->
linux-2.4-xfs/linux
lrwx------   1 root     root           10 Jul 10 00:27 /usr/tmp ->
../var/tmp
# ll -d /var/tmp /usr/src/linux-2.4-xfs/linux 
drwxr-xr-x  16 root     root         4096 Jul 21 09:09
/usr/src/linux-2.4-xfs/linux
drwxrwxrwt   2 root     root         4096 Jul 21 10:06 /var/tmp

I'm used to mode 777 for a symlink. Why here 755 and 700 and only the
mode of /usr/src/linux matching the mode of the dir it points to?
