Currently, the clause agent concerns thing requires thing to be a message, which is a valid & expected use case. However, a common use case is for an agent to concern an entity. In this scenario, a message must be created that is from the entity solely for the purpose of allowing the agent to concern the message. Instead, the agent should be able to concern the entity directly, avoiding the unnecessary declaration message thing from thing.
