The XML-DEV Blog

The XML-DEV email discussion forum was started nearly 10 years ago by Dr. Peter Murray-Rust and Dr. Henry Rzepa of Imperial College (UK), covering XML development topics including XML standards, XML specifications, and technical questions related to the eXtensible Markup Language. The XML-DEV Blog brings the XML-DEV community into the blogging era, enabling XML developers to easily follow the hottest threads in the blogosphere.
