They are improvements because they make the typing weaker. They make it 
much easier to tie the XML documents to classes of your choice, with 
method invocations, configuration, and initialization that you want to 
do. They are much more flexible and much less fixed. (Digester much more 
so than JAXB 2.0.)

For Digester, see Herve Agnoux's article (in French)

http://beuss.developpez.com/tutoriels/java/jakarta/commons/digester/

For JAXB 2.0 Kohsuke Kawaguchi has written quite a bit in his blog: 
http://weblogs.java.net/blog/kohsuke/

See, in particular,

http://weblogs.java.net/blog/kohsuke/archive/2005/09/using_jaxb_20s.html

"Sometimes when you are binding your own classes to XML, you hit with a 
situation where your class representation doesn't quite match what you'd 
like to see in the XML. Some other times, some of your classes hit the 
limitation in JAXB that the class must have a default constructor. 
XmlJavaTypeAdapter is a solution for those problems."
