       access for everyone. The method "Allocate" makes sure that the ACL is
       allocated (so that it does not grant access for everyone). The method
       "Deallocate" makes sure, that the ACL is freed, as a result everyone has
       access. The method "Clear" makes sure that the ACL is allocated, but empty,
       as a result the ACL grants access to no one.</p>
