The Binding Element

The Operation element typically consists of an Input element and an Output element, which, using Message and Part elements, describe the input required by the operation (a ticker symbol, for example) and the output returned by it (a stock value, for example).

How to Create a Binding Element

To create a Binding element:

1. Select the Definitions (root) element.

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

Alternative: Right-click the Definitions element and choose Add > Operation from the shortcut menu.

Stylus Studio adds a Binding element to the WSDL as a child of the Definitions element. The default name is Binding-0, but you can change it. Binding names must be unique within a WSDL document.

How to Rename a Binding Element

To rename a Binding element:

1. Double-click the Binding element in the WSDL diagram.

The name becomes editable.

2. Type a new name and press enter.

Alternative: Using the Properties window

1. Display the Properties window if it is not already open. (View > Properties).

2. Change the Binding name in the Value field in the Properties window.

Alternative: You can change the Binding name directly in the WSDL text.
