Okay ... So, I am late
. I would have taken a day off from my day job if I knew that there would be so many questions.
Coming to the main question -- what XML Security technologies are covered?
You will find pretty good coverage of XML-Signature, XML-Encryption and WS-Security with sample code and examples. SAML and XACML are mentioned in the passing, but not covered in detail, the main reason being the lack of good
Java toolkits, either open source or commercial, supporting these standards at the time of finalizing the manuscript.
