I would be interested to find out more details of these requirements and if
anyone else has come up with similar requirements.

In terms of access control and dominance, this is the wrong approach. The
security classification defines the degree of sensitivity, and as such it is
hierarchical. The security category further refines the access but is
non-hierarchical. Dominance is not just carried out based on a hierarchical
sensitivity level. Making security categories hierarchical feels proprietary
to me.

Problem solved then - have a big list of classifications ;-)
