This part introduces XQuery as an alternative to XSLT for transformation of messages. Validation of request messages in the Mediator comes up next, either using the XSD Schema Definition or using the more advanced Schematron definitions. Fault handling in SOA composites is introduced – to deal with validation errors. And finally, to aid our run time understanding of the instances of the SOA composite application, Composite Sensors are used to add meta data to these instances.
