/**
*
* This example demonstrates the processing of an order for books using
* several of the components provided by the Spring Integration Xml
* module for dealing with Xml payloads. This includes:
*
* <ul>
* <li>an XPath based implementation of the splitter pattern to split an
* order with multiple items into several order messages for separate
* processing.</li>
* <li>XPath expression namespace support to build an XPath expression to
* extract the isbn from each order item.</li>
* <li>an XPath router implementation to route messages according to the
* evaluation of an XPath expression which tests to see if the order item is in
* stock.</li>
* <li>an XSLT transformer implementation to transform the payload of the
* order message into a resupply message where the order item is found to be
* out of stock.</li>
* </ul>
