Can be set to true for those constraint components where the validation does not require to visit any other triples than the parameters. Examples of this include sh:datatype or sh:nodeKind, where no further triples need to be queried to determine the result. Constraint components that are marked as such can be optimized by engines, e.g. they can be evaluated client-side at form submission time, without having to make a round-trip to a server.
