The Types Element

You use the Types element to specify the XML Schema ( xsd:schema) that is used to describe the structure of a WSDL Part.

A WSDL document can have only one Types element; it must be named "types."

How to Create a Types Element

To create a Types element:

1. Select the Definition (root) element.

2. Select Diagram > Add > Types from the Stylus Studio menu.

Alternative: Right-click the Definition element and choose Add > Types from the shortcut menu.

Stylus Studio adds a Service element to the WSDL.

Types Element Properties

The Types element has no editable properties.

Adding a Schema Element

Once you add the Types element to the WSDL, you then add one or more Schema elements. A Schema element represents an XML Schema, and is created using the xsd namespace by default:


<wsdl:types> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"/> </wsdl:types>

Once it is part of the WSDL definition, you work on a Schema element as if it were an XML Schema in Stylus Studio. For example, you can either define the XML Schema's elements, attributes, global types, and so on directly in the WSDL, as shown in Figure 382, or you can use the Schema element to reference existing XML Schemas ( Diagram > Reference Schemas).
