"The book addresses a sorely missing set of considerations in the real world ... This is a very timely book."--Peter Herzum, author of Business Component Factory and CEO of Herzum SoftwareXML is a tremendous enabler for platform agnostic data and metadata exchanges.

This book describes the challenges of using XML in a manner that promotes simplification.
