    Is not *-one-and-only just guarantee you that there is exactly one value
    in a bag?  What would you do with two values for current-time?

    Subject: [xacml] default environment attributes and explicit attributes
    
    Is the intent that default environment attributes should only be created
    
    on an "as needed" basis?  For example, looking at the test suite, 
    default time, etc., are needed for IIA017 019 and 021.  If we always add
    
    the time, then tests 016 018 and 020 fail, because the request message 
    includes a time, and the policies do time-one-and-only.
    
    Are we missing something in the spec, or are the tests wrong?
    
    Thanks.
