SDO doesn't require validation at any particular time, so it's up to the 
implementation. The primary use of the createFromString() and 
convertToString() methods is to support XML deserialization and 
serialization respectively. We don't want to slow down load performance if 
we don't need to, and since the SDO Month type's instanceClass is 
java.lang.String, we simply assume it's valid and return the same string 
in createFromString - see ModelFactoryImpl.createMonthFromString().
