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 REF: 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.
