E.10.D2:4.1.1 - EntityOfConcern
EntityOfConcern is the one exact independently identified U.Entity about which the selected claim-bearing whole makes its claims. It may be a system, work occurrence, method, episteme, direct relation occurrence, characteristic, structure, pattern, or another admitted entity. It is neither a universal object bucket nor the authoring target merely because the author is editing it.
A ClaimGraph may designate several other entities as participants in relational, comparative, negative, counterfactual, or modal claims. Those designations do not by themselves create a joint EntityOfConcern. Select a relation occurrence, collection, or structured whole only after its direct pattern independently identifies that entity.
