+/** allows to make UNO objects persistent
+
+  <p>Every UNO object, that wants to be serializable, should implement
+     this interface. The object stores stores itself, when the
+     write method is called.
+     <p>
+     The object needs to be created before it deserializes
+     itself again (by using the read method). Therefore it must be
+     creatable by name via a factory, which is in general
+     the global service manager. The create and read mechanism
+     is implemented by the com::sun::star::io::ObjectInputStream.
+
+     <p>The serialization format (the series of strings, integers, objects) must
+     be specified at the specification of the concrete service.
+
+     <p>The interface does not support any special versioning mechanism.
