The expression return '<p> <label for='...'>'.$description.'</p>' returns the type string which is incompatible with the return type mandated by Anax\HTMLForm\FormElement::getHTML() of Anax\HTMLForm\HTML.
                                                                                                                                                                                                                                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
In the issue above, the returned value is violating the contract defined by the
mentioned interface.


Let's take a look at an example:


interface HasName {
    /** @return string */
    public function getName();
}

class Name {
    public $name;
}

class User implements HasName {
    /** @return string|Name */
    public function getName() {
        return new Name('foo'); // This is a violation of the ``HasName`` interface
                                // which only allows a string value to be returned.
    }
}
