Sorry... All Elements have groups. All users have groups. And if one
element have the same group of any user, this user can have permissions
in this group for: read, write, execute, recycle, delete, chmod, chown,
root and guest. All elements and all users have groups.

This access permissions don't are in the element.. depend the user to
access. The permissions are stored by user -> group don't by file or
file -> group.
An user can read or not any record, field , table.. if an user don't
have any group equal to any element group, don't see it!
