You can add an attribute reference to a message, complex type or complex element. This task assumes that you have previously added the relevant message, complex type or complex element to your message model.
To add an attribute reference to a message, complex type or complex element:
Switch to the Enterprise Service Tools perspective.
In the Outline view, right-click the message model object (message, complex type or complex element) to which you are adding the attribute reference then click Add Attribute Reference on the pop-up menu. This adds a default attribute reference to the message model object that points to an existing global attribute.
You can now configure the local element to your exact requirements. For further information on configuring message model objects see Configuring message model objects.
