description: Declares a relation that associates a `Thing` (or another attribute)
with an attribute, where an attribute is an intrinsic characteristic, such as
a quality, capability, disposition, function, or is an externally derived attribute
determined from some descriptor (e.g. a quantity, position, label/identifier).
Technically, this declaration is done via an `AttributeSpecification` that combines
a `predicate` with a value declaration and the attribute-related slots of a
`Thing`. Importantly, such attributes are declared inline, because they do not
have a unique identifier. If an identifier is available, a `Thing` declaration
(see `relation`), and a qualification of that relationship via a `Statement`
(see `characterized_by`) should be preferred.

purposes. This is used to indicate specialized schema classes for properties
