XACML standard

Hi,

This is the worst standard I have ever seen. There is literally no documentation available to get beginners to use it. The implementations listed on the website are all half-assed, and some are non existent. I can't believe how much time I wasted this semester
 trying to research into XACML, it ruined the grade for one of my classes. I hope I never have to use this useless standard ever again.

Thanks for nothing,

Sagar
