  To give an example from a previous life, GE uses 6 vertical levels
("Class 1" thru "Class 6") for company information.  The lowest level
is releasable information, as I recall, and the highest is very very
closely held trade secrets.

  We should not get locked into using CIPSO because it is not the only
game in town.  In particular, most of the DoD has invested in IPSO
(RFC-1108).  We need to avoid getting locked into any particular IP
labelling scheme.  Actually, there are very serious trust issues with
any unprotected IP option in this context.  We need to be careful to
distinguish "trusted" from "trustworthy".
