 * </code>
 *
 * We have defined some commonly used base permissions which you can use:
 * - VIEW: the SID is allowed to view the domain object / field
 * - CREATE: the SID is allowed to create new instances of the domain object / fields
 * - EDIT: the SID is allowed to edit existing instances of the domain object / field
 * - DELETE: the SID is allowed to delete domain objects
 * - UNDELETE: the SID is allowed to recover domain objects from trash
 * - OPERATOR: the SID is allowed to perform any action on the domain object
 *             except for granting others permissions
 * - MASTER: the SID is allowed to perform any action on the domain object,
 *           and is allowed to grant other SIDs any permission except for
 *           MASTER and OWNER permissions
 * - OWNER: the SID is owning the domain object in question and can perform any
 *          action on the domain object as well as grant any permission
