The VerifierContext provides several facilities. First, it may be used to pass custom context information into a Verifier via the CustomContext property. It may also be used within the verifier to see the results of any previously executed verifiers within the current VerifierEngine batch via the VerifierResults property. A batch is defined as the list of all of the verifiers executing within a single VerifierEngine.Execute method call. The VerifierErrorContinuationMode may be used to terminate the execution of the batch by setting the ErrorContinuationMode property to VerifierErrorContinuationMode.Stop and returning an “errant” VerifierResult. Lastly, the BatchContext property may be used to build up any cumulative data that we want passed to the next verifier within the current batch. The first verifier in a batch will always receive a null BatchContext.

The default VerifierContext that is provided by the VerifierEngine when no explicit VerifierContext is specified is constructed automatically by the engine using the VerifierOptions.ErrorContinuationMode and VerifierEngine.DefaultCustomContext properties on the VerifierEngine.
