What a nice surprise! I found a kind of quick tutorial about Atabaque DTDtoBean at Toni Epple's blog, address http://eppleton.com/blog/?p=116.
Atabaque DTDtoBean generates JavaBeans from a specified DTD file. You can choose generate standard Java Beans or using Annotations for XStream or Simple, APIs for XML Serialization. It´s available as a command line, Swing application or NetBeans plugin.
The second Atabaque DTDtoBean beta version optionally generate code for Property Change Support in Java Beans, mandatory for using with BeansBinding (JSR 295). Hope you enjoy it!
The first Atabaque DTDtoBean tool is available. You can see Screenshots and a brief documentations, in Projects/Screenshots and Documentation/Browse options, respectively.
