// If the checker class is already provided, likely we have been included in a separate composer project
if (!class_exists(\DoctrineXml\Checker::class)) {
    // Otherwise, lets try to load composer ourselves
    if (!@include(DIR_BASE_CORE . '/' . DIRNAME_VENDOR . '/autoload.php')) {
        echo 'Third party libraries not installed. Make sure that composer has required libraries in the concrete/ directory.';
        die(1);

    include_once (DIR_BASE . '/' . DIRNAME_VENDOR . '/autoload.php');
}
