Create new managed classes, either from scratch or through the copy and paste of another site-defined managed class. Single class inheritance is supported and required, such that when defining a class, the administrator must indicate which existing managed class it extends. The derived class includes all properties included in its base class.

Delete managed classes, but not the fixed managed classes (those supplied with the product).

Add user properties (integer, Boolean, or string) to a site-defined managed class. There is no limit to the number of properties that can be defined for a managed class. The administrator can define the text of the property description that is displayed when the property is selected in the Details pane, and the category under which it is displayed. If a property is later added to a base class, it is automatically included in all classes derived (directly or indirectly) from it.

Delete user properties from a managed class. If a property is later deleted from a base class, it is automatically removed from all classes derived from it.
