Defining complexTypes That Contain Elements and Attributes - Tree View

The purchaseOrder.xsd sample document contains the following complexType definition. This complexType defines three elements, refers to a fourth element, and defines an attribute.

<xsd:complexType name="PurchaseOrderType">  
<xsd:sequence>  
<xsd:element name="shipTo" type="USAddress"/>  
<xsd:element name="billTo" type="USAddress"/>  
<xsd:element ref="comment" minOccurs="0"/>  
<xsd:element name="items" type="Items"/>  
</xsd:sequence>  
<xsd:attribute name="orderDate" type="xsd:date"/>  
</xsd:complexType>

In the Tree view, to define a complex type with a similar structure:
1. Click the Schema node.
2. In the left tool bar, click New complexType . In the Tree view, Stylus Studio displays a field for the new complexType.
3. Type a name for this new complexType and press Enter.
4. In the left tool bar, click New Model Group . Stylus Studio displays a pop-up menu that lists the group modifiers.

You can specify any number of modifiers in a complexType. Each modifier controls the occurrence of its child nodes. You can specify the same modifier more than once. For example, you might want to specify the sequence modifier, with some child nodes, then the choice modifier with some child nodes, and then the sequence modifier again with other child nodes.

6. For each element that you want to define in this complexType with the selected modifier, perform the following steps:
a. Click the modifier name in the Tree view.
b. In the left tool bar, click New Element Definition . In the Tree view, Stylus Studio displays a field for the new element definition.
c. Type a name for the new element and press Enter. Stylus Studio displays a pop-up menu that lists the built-in simpleTypes and simpleTypes you defined.
d. Double-click the type for the new element.
e. In the Properties window, you can double-click the field for any property to set the value for that property.

For example, you can specify 0 for the Min Occur. property and 1 for the Max property. The effect is that the element is optional.

a. Click the modifier name in the Tree view.
