Stephen Tweedie gave a talk back in 2000 which covered revoke records.
There's a transcript of his talk here:

http://olstrans.sourceforge.net/release/OLS2000-ext3/OLS2000-ext3.html

The link to the audio file of the talk is dead, but I managed to find
a copy of the mp3 file on Google.  To make sure it doesn't get lost
I've made a copy of it.  The original and the copy can be found at:
