Redefining Types |
In this section, you will learn how to redefine a type from one schema in another schema. You will also learn how to add a new element to a redefined type. This is also done in XMLSpy. For the purpose of this tutorial, we will use the schema book_order.xsd as an example.
Notice that the schema contains a redefine statement, which was automatically added when you connected the two schemas in the Redefine section discussed previously.
To redefine the type PersonInfoType:
| 2. | Select the line that says "end of redefine" and click the Insert  icon. |
| 3. | Select ComplexType from the menu that pops up and enter "personInfoType" as the name for this type. |
| 4. | Click the Display Diagram  icon for personInfoType. |
The content model of personInfoType, as defined in event_registration.xsd, appears.
| 5. | Right-click the  complexType, and select Add child | Sequence from the context menu. |
| 6. | Right-click the new sequence icon and select Add Child | Element from the context menu. |
| 7. | Enter "customerNumber" as the name for this element. |
| 8. | In the Details entry helper, select xs:string from the type drop-down list. |
| 9. | Save the file. |
You have now redefined personInfoType to be used as a type in the XML schema book_order.xsd.
