/**
 * Second example: inline schema addressing
 *
 * <p><a href="doc-files/Example2.java">link to source code</a></p>
 *
 * <p>This example uses the same schema with one difference: the mntent
 * subschema is now referenced via inline addressing using an {@code id}.</p>
 *
 * <p>The schema used for validation is <a href="doc-files/fstab-inline.json">
 * here</a>.</p>
 *
 * <p>In order to use inline schema addressing, we cannot use the default
 * factory: we must go through a {@link JsonSchemaFactoryBuilder} and use a
 * modified {@link LoadingConfiguration} to tell that we want to use inline
 * dereferencing.</p>
 *
 * <p>Apart from these, the files used for validation and validation results
 * are the same as {@link Example1}.</p>
