(See previous comments on the distinctino between Objective (the O in
SLUO) and design guidelines.)

Jan makes an important point:

We could think of the RM as enabling applications to provide operational
definitions of what it means for nodes 'to have a subject' or for two
nodes to 'have the same subject.'
