 * Interface for storing values associated to an identity constraint.

 * is created for each identity constraint per element declaration in
 * the instance document to store the information for this identity
 * constraint.
 * <p>
 * <strong>Note:</strong> The component performing identity constraint
 * collection and validation is responsible for providing an 
 * implementation of this interface. The component is also responsible
 * for performing the necessary checks required by each type of identity
 * constraint.
