Overview

The NumberOfAttributeValues type (basic:NumberOfAttributeValues prior to V3.2) is a PolicyRule which returns true If the number of values for the specified attribute falls between specific limits. This can be used for sanity checking of results, for instance to refuse to release any values if not all possible values are present.
