I'm a member of the team at IBM that builds a security policy management solution, including XACML for authorization policy; and I used to be the team lead for the XACML runtime component itself. The product is called Tivoli Security Policy Manager, and is definitely under active development.
This has been answered on the XACML TC list already: http://markmail.org/message/w7msffsbi6qzgfoj.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
