The SIDP values that reflect the subjects of a-nodes and c-nodes, and that, therefore, determine whether they should be merged, can only be conferred upon them by virtue of their service as the A and C endpoints of arcs. This RM4TM defines the merging rules for assertions (see parid0374 5.2.8.2), and conforming TM Applications cannot violate these rules. Therefore, TM Applications cannot require the values of the subject identity discrimination properties (SIDPs) of a-nodes or c-nodes to be conferred upon them on the basis of their situations as role players (i.e. on the basis of their service as the x endpoints of Cx arcs).
SIDP values, which determine the subjects of a-nodes and c-nodes, can only be conferred by service as a-nodes or c-nodes. That such nodes may also be role players (x endpoints of Cx arcs) may not be used to confer SIDP values.
Attempt to shorten and focus the prose.
