/**
 * Second example: inline schema addressing
 *
 * link to source code
 *
 * This example uses the same schema with one difference: the mntent
 * subschema is now referenced via inline addressing using an {@code id}.
 *
 * The schema used for validation is 
 * here.
 *
 * 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.
 *
 * Apart from these, the files used for validation and validation results
 * are the same as {@link Example1}.
 *
 * @see Dereferencing
