/**
 * Tenth example: registering schemas
 *
 * <p><a href="doc-files/Example10.java">link to source code</a></p>
 *
 * <p>In this example, we register a custom schema into our factory with a
 * given URI, and initiate the schema instance using that URI.</p>
 *
 * <p>The only necessary condition for the URI is for it to be an absolute JSON
 * reference (see {@link JsonRef#isAbsolute()}), and you can register as many
 * schemas as you want. Here, we register both schemas from {@link Example5}.
 * You will notice that the scheme for these URIs is {@code xxx}: it does not
 * matter in the slightest that it is not a supported scheme by default, the
 * schema is registered all the same.</p>
 *
 * <p>This also shows that reference resolution still works in such a case,
 * since the {@code mntent} schema is referred to via a relative URI from the
 * {@code fstab} schema.</p>
 *
 * @see Builder#addSchema(String, JsonNode)
 * @see Builder#addSchema(URI, JsonNode)
