Overview
The NumberOfAttributeValues type 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.
Reference
XML Attributes
Name | Type | Required? | Description |
|---|---|---|---|
attibuteID | String | Y | The name of the attribute whose values are to be counted |
minimum | Non-negative (>=0) Integer | Y | The minimum number of values allowed |
maximum | Non-negative (>=0) Integer | Y | The maximum number of values allowed |
The policy returns true iff the number of values is >= 'minimum' and  the number of values is  <= 'maximum'.
Example
Apply this rule if the attribute "uid" has 1, two or 3 attribute values, otherwise not:
<PolicyRequirementRule xsi:type="NumberOfAttributeValues" attributeID="uid" minimum="1" maximum="3"/>
