A new "Meet the Engineer" Q&A I did with a java.net blogger appears on java.sun.com here if you want to check it out:

I interviewed Kohsuke Kawaguchi, who has worked with XML schema languages since 2001, including specification work on RELAX NG
and W3C XML Schema, and implementation work in a number of related Java artifacts, including JAXB (Java Architecture for XML Binding) and JAXP (Java API for XML Processing).

He's a lively and imaginative guy who was an entrepreneur in high school and college in Japan. He has interesting things to say about schema languages, work ethic differences between the US and Japan, the Stapler and JAXB projects, and more.
