* <p>A sample demonstrating how to use the JAXP 1.3 Validation API
* to create a validator and use the validator to validate input
* from SAX, DOM or a stream. The output of this program shows the
* time spent executing the Validator.validate(Source) method.</p>
*
* <p>This class is useful as a "poor-man's" performance tester to
* compare the speed of various JAXP 1.3 validators with different
* input sources. However, it is important to note that the first
* validation time of a validator will include both VM class load time
* and validator initialization that would not be present in subsequent
* validations with the same document. Also note that when the source for
* validation is SAX or a stream, the validation time will also include
* the time to parse the document, whereas the DOM validation is
* completely in memory.</p>
*
* <p><strong>Note:</strong> The results produced by this program
* should never be accepted as true performance measurements.</p>

/**
* <p>A sample demonstrating how to use the JAXP 1.3 Validation API
* to create a validator and use the validator to validate input
* from a DOM which contains inline schemas and multiple validation
* roots. The output of this program shows the time spent executing
* the Validator.validate(Source) method.</p>
*
* <p>This class is useful as a "poor-man's" performance tester to
* compare the speed of various JAXP 1.3 validators with different
* input sources. However, it is important to note that the first
* validation time of a validator will include both VM class load time
* and validator initialization that would not be present in subsequent
* validations with the same document.</p>
*
* <p><strong>Note:</strong> The results produced by this program
* should never be accepted as true performance measurements.</p>
