Hi Blair

thanks for your comments. I have one question below

I would like to clarify the above. The site where an authz assertion is 
validated and consumed must be the resource site. Correct? So you are 
saying that the resource site has no control over which roles give 
permissions to access it, and instead it trusts an external TTP to say 
who has permission to access it. Is this your model?

regards

David
