use Boekkooi\Bundle\TwigJackBundle\Validator\Constraint as TwigAssert;
use Symfony\Component\Validator\Constraints as Assert;

class MyClass {
    // ...

    /**
     * [@Assert](https://github.com/Assert)\NotBlank()
     * [@TwigAssert](https://github.com/TwigAssert)\TwigSyntax()
     */
    public $template;

    /**

     *
     * [@Assert](https://github.com/Assert)\NotBlank()
