The WebSphere® Transformation Extender data binding descriptor is a URI that describes the incoming message.
The WebSphere Transformation Extender data binding descriptor is set by the client in the headers of the incoming message. It provides the information required to associate the incoming message with the correct map in the WebSphere Transformation Extender.
Using the WebSphere Transformation Extender data binding descriptor is one of two ways that you can set the invocation of the map. The alternative is to configure the properties of the WebSphere Transformation Extender data handler in WebSphere Integration Developer. However, you should use the WebSphere Transformation Extender data binding descriptor when you want to use a different map for each invocation of the operation.
For example, consider an export with an operation Create(Customer). If you want every invocation of this operation to use the same WebSphere Transformation Extender map for each customer, then configuring the properties of the WebSphere Transformation Extender data handler in WebSphere Integration Developer is an appropriate choice.
However, you might want to invoke a different map depending on the customer. In this case the operation is invoked with customer and uses a different map for every invocation. Such a scenario cannot be configured in the properties of the data binding and you must instead use the data binding descriptor.
