Data Quality and XML Validation

When the pressure is on, getting the messages flowing seems to be everyone's priority. XML Security is a huge and important side topic examining the problems associated with ensuring XML messages can move untampered between clearly identified and fully authorised agents. Data Quality is the next most important issue: does the message contain valid, timely, meaningful and eventually useful data? How can we implement a data quality architecture to support these concepts? Looking at the use of XML on both individual projects and also from the perspective of enterprise architecture, the topic of data quality will be discussed from business importance through to practical guidelines.
