Quarterman) From: kingdon@ai.mit.edu (Jim Kingdon) Thanks for providing some technical details. But can't the level be made a special case of the set of categories? That is, define categories CLASSIFIED, SECRET, TOP_SECRET, etc, and give people either {TOP_SECRET, SECRET, CLASSIFIED} or {SECRET, CLASSIFIED} or {CLASSIFIED}. Unless I'm missing something, this provides the same functionality and is simpler. You might want to post a clarification (or summary of this and other messages). Volume-Number: Volume 20, Number 107
