38: * Base implementation of the menu item rule.<p>

40: * This was introduced because of the possible sub-menus.

42: * {@link #getVisibility(CmsObject, CmsResourceUtil[], I_CmsMenuItemRule[])}.
43: * This default base implementation just calls the standard visibility method
44: * discarding the additional rules.<p>
