i did get the option of revoking every time without enough authority though...and we couldnt expand our vclaim to cover even the half of the pclaim due to its hugeness at first. once you get the option, it tells you how much authority you need to revoke when you do not have sufficient authority. (we tried revoking many times only to get reminded how much more authority we needed. unfortunately, w3 ended before we managed it.)
maybe revoking system was changed without announcement since w3.(or i may have missed it...)
