/**
 * Third example: draft v4 detection via $schema
 *
 * link to source code
 *
 * This shows a basic usage example. This is the same source code as for
 * {@link Example1}, except this time the schema (here) conforms to draft v4 instead of
 * draft v3 (the {@code $schema} value differs).
 *
 * 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.
