UAF14 — toBe Attribute is an Attribute of the Architecture Not the Architecture Description

toBe: Boolean[1] Indicates whether the ArchitecturalDescription represents an Architecture that exists or will exist in the future.

This is incorrect. This is a property of the Architecture not the ArchitectureDescription i.e. an ArchitectureDescription of a future Architecture not a future ArchitectureDescription of an Architecture.

This is another consequence of not differentiating properly between 'architecture' and 'architecture description'.
