I reread the slide and I see now that you mean what you said: the 
revoker does not provide any "actual" file authority. I disagree: 
revocation-authority should still be considered actual authority over 
the file, as it can not only influence who can access the file but 
indirectly also the content of the file. It would be different probably 
if the revoker could only affect the read authority.
