| * <h2>Default value handling</h2> |
| * <p> |
| * Since unmarshaller just adds new values into the storage, |
| * we can't fill the storage by default values at the time of |
| * instanciation. (or oherwise values found in the document will |
| * be appended to default values, where it should overwrite them.) |
| * <p> |
| * Therefore, when the object is created, the storage will be empty. |
| * When the getXXX method is called, we'll check if the storage is |
| * modified in anyway. If it is modified, it must mean that the values |
| * are found in the document, so we just return it. |
| * |
| * Otherwise we will fill in default values and return it to the user. |
| * |
| * <p> |
| * When a list has default values, its dirty flag is set to true. |
| * Marshaller will check this and treat it appropriately. |
