* ONETIME properties are a sort of conglomeration of READONLY
* and INHERIT. They can be set only during object creation,
* after that they are READONLY. If not explicitly set during
- * creation, they can be inherited.
+ * creation, they can be inherited. ONETIME_DEFAULT properties
+ * work the same way, but they will default instead of
+ * inheriting a value.
