62  * Interface for storing values associated to an identity constraint.
63  * Each value stored corresponds to a field declared for the identity
64  * constraint. One instance of an object implementing this interface
65  * is created for each identity constraint per element declaration in
66  * the instance document to store the information for this identity
67  * constraint.
68  * <p>
69  * <strong>Note:</strong> The component performing identity constraint
70  * collection and validation is responsible for providing an
71  * implementation of this interface. The component is also responsible
72  * for performing the necessary checks required by each type of identity
73  * constraint.
