A.3.3.CC:9 - Consequences

The description makes compatibility usable: a solver can seek a fitting arrangement, a practitioner can locate the condition excluding one, and another participant can reconstruct the represented values. A later law of change starts from interpretable configurations.

Construction takes effort, particularly when constraints interact or a compact representation loses necessary detail. An implicit description may save modeling effort while making each computation harder; a parametrization reverses that trade-off. Reuse an adequate description until a changed operation, premise or required distinction defeats it.
