The existence of a given assertion never implies anything about the subject which is the assertion type (if any) of which the assertion is an instance, or about the subjects that are the assertion's role types. No values can be conferred upon the SIDPs of assertion types or role types by virtue of their situations, respectively, as the T endpoints of AT arcs, or as the R endpoints of CR arcs.

Should appear in section on SIDPs (parid0223).
