Symfony2占位符html

Question

I need your help. I have build a form of user registration. I need to add checkbox with this massage: "Accept the terms of use" but the word of "terms" must be link to pdf file. Of course I can't put html tags into translation file because it doesn't work. I could use 'raw' keyword in twig template. But I don't want to doing this. I am thinking about placeholder to do it. But I do not now how to made it form class. Do you have any idea how to do it?

class SupplierAddressFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        parent::buildForm($builder, $options);
         $builder->add('roules_acceptance', 'checkbox', array('label' => 'form.roules_acceptance', 'mapped' => false));
         // ....
    }
}

example of label what I need to made:

Accept the <a href="url_to_pdf">terms</a>
