## ElementsRequiredAttribute Class

Applied to an array, collection, or otherwise enumerable property, field, or parameter to declare that
the collection itself must be non\-null and contain at least one element, and that no element inside it
may be null\. Useful for protocol metadata such as `redirect_uris` where an empty array is invalid\.
