That (should) mean that session cookies are exempt. A basic install of Xoops (should) only set a session cookie.
However, I can see that your concerns are valid and that the information officer for the Dutch government really needs to clarify the issue. If they really do require every site to have a cookie warning, then they will seriously damage the opportunities of Dutch businesses that own websites.
I am sure I am not the only person that will treat such a warning as a security risk and quickly go back to the search listing.
