[CentOS] SELinux context not applied

Hi,

I tried to apply a security context on a directory with the following
commands:

[root@ local]# semanage fcontext -a -t httpd_sys_rw_content_t "netdot(/.*)?"
[root@ local]# restorecon -R netdot/


When I list the contexts, it is part of the list....
[root@ local]# semanage fcontext -l | grep netdot
./netdot(/.*)?                                     all files
system_u:object_r:httpd_sys_rw_content_t:s0


... but does not appear on the directory itself:
[root@ local]# ls -ldZ netdot/
drwxr-xr-x. root root unconfined_u:object_r:*usr_t*:s0   netdot/


I am expecting to see something like:
drwxr-xr-x. root root unconfined_u:object_r:*httpd_sys_rw_content_t*:s0
netdot/


What am I doing wrong or do not understand?

Thanks,
