    All,
    
    I got a comment from one of our customers regarding the new XACML 3.0 cd 
    1 attribute assignment expression.
    
    It says in section 5.41 that "The expression MUST NOT evaluate to a 
    bag". The customer suggested, and I agree, that the expression should be 
    allowed to evaluate to a bag, in which case the result would be a 
    multiple attribute assignments in the obligation/advice.
    
    This is useful for instance if one wants to relay back values from the 
    incoming request into an obligation since the incoming attributes in the 
    request can be multi valued.
    
    I am adding this to my collection of feedback on the public review.
    
    Best regards,
    Erik
