    40  * Dummy implementation of {@link DatatypeStreamingValidator}.

    41  *

    42  * <p>

    43  * This implementation can be used as a quick hack when the performance

    44  * of streaming validation is not important. And this implementation

    45  * also shows you how to implement the DatatypeStreamingValidator interface.

    46  *

    47  * <p>

    48  * Typical usage would be:

    49  * <PRE>{@code

    50  * class MyDatatype implements Datatype {

    51  *     ....

    52  *     public DatatypeStreamingValidator createStreamingValidator( ValidationContext context ) {

    53  *         return new StreamingValidatorImpl(this,context);

    54  *     }
