The configuration sample shown in Example 5.5, “Simple Router Configuration” can be explained as follows:

	The `transformers` element defines two transformers that are used in the route. One transformer converts the message data `InputStream` into a string. The other transformer reverses the process.
	The `mule-descriptor` defines a route.
	The `implementation` attribute specifies the Java class that implements the route's UMO. In this example, the UMO is a simple pass through.
	The `inbound-router` element defines the endpoint that acts as the service provider for the route.
	The `endpoint` element specifies how the service provider endpoint is to be set up. The `address` attribute specifies where the WSDL contract defining the service interface used by the endpoint is located.
	The `transformers` attribute specifies that messages received by this endpoint will be passed through the `InputStreamToString` transformer before it is handed off to the UMO.
	The service property specifies the QName of the `service` element that defines the endpoint in the WSDL contract.
	The port property specifies the QName of the `port` element that defines the endpoint in the WSDL contract.
	The dataFormat property specifies that this endpoint uses the message data mode.
	The `router` element specifies the class that implements the functionality of the outbound router. In this case the outbound router is a pass through router.
	The endpoint's `transformers` attribute specifies that messages passing into this endpoint will pass through the `StringToInputStream` transformer.
	The dataFormat property specifies that the endpoint uses the message data mode. The setting for this property must match the setting in the inbound router's endpoint.
