/**
 * Third example: draft v4 detection via $schema
 *
 * <p><a href="doc-files/Example3.java">link to source code</a></p>
 *
 * <p>This shows a basic usage example. This is the same source code as for
 * {@link Example1}, except this time the schema (<a
 * href="doc-files/fstab-draftv4.json">here</a>) conforms to draft v4 instead of
 * draft v3 (the {@code $schema} value differs).</p>
 *
 * <p>One thing to note is a difference in the validation messages: while
 * required properties were in charge of the {@code properties} keyword for
 * draft v3, it is now in charge of the {@code required} keyword.</p>
