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).
