/**
* Dummy implementation of {@link DatatypeStreamingValidator}.
*
*
* This implementation can be used as a quick hack when the performance
* of streaming validation is not important. And this implementation
* also shows you how to implement the DatatypeStreamingValidator interface.
*
*
* Typical usage would be:
*
* class MyDatatype implements Datatype {
* ....
* public DatatypeStreamingValidator createStreamingValidator( ValidationContext context ) {
* return new StreamingValidatorImpl(this,context);
* }
* ....
* }
