Using Redefined Types |
In the previous section, you redefined schema event_registration.xsd in schema book_order.xsd by adding a customer number to the complex type personInfoType. In this section, you will learn how to use this redefined complex type in schema book_order.xsd.
To use a redefined type in the target schema:
| 1. | In the schema overview for book_order.xsd, click the Display Diagram  icon of the root element book_order. |
| 2. | Right-click the sequence element and select Add child | Element from the context menu. |
| 3. | Enter "customerInfo" as the name for this element. |
| 4. | With this element still selected, in the Details entry helper, select personInfoType from the type drop-down list. Components from both schemas are in black, all others are in blue. |
The redefined type is now being used as the type of an element in book_order.xsd.
Using types without redefinition
Within a redefine relationship, you can also use types from the source schema without redefining them in the target schema.
To use a type in the target schema as is:
| 1. | In the display diagram for the element book_order, right-click on the sequence element and select Add child | Element from the context menu. |
| 2. | Enter "creditCardInfo" as the name for this element. |
| 3. | With this element still selected, in the Details entry helper, select creditCardInfoType from the type drop-down list. |
| 4. | Save the file. |
The type creditCardInfoType is now being used as the type of an element in book_order.xsd.
