+\class QScriptDeclarativeClass::Value
+\internal
+\brief The QScriptDeclarativeClass::Value class acts as a container for JavaScript data types.
+
+QScriptDeclarativeClass::Value class is similar to QScriptValue, but it is slightly faster.  
+Unlike QScriptValue, however, Value instances cannot be stored as they may not survive garbage 
+collection.  If you need to store a Value, convert it to a QScriptValue and store that.
