AngularJS: Directive - Passing strings without having to use quotes

Question

Here's a directive I created:

HTML:

<p-test something="'bla'"></p-test>

JavaScript:

.directive('pTest', function() {
    return {
        scope: {
            something: '=?'
        },
        templateUrl: 'components/testTemplate.html',
        controller: 'testController'
    };
});

I'd like to be able to pass 'bla' as a string without the '', in the following way:

<p-test something="bla"></p-test>

I know it's possible via the attributes parameter in link, but it's irrelevant in this case (correct me if I'm wrong) as I'm passing these parameters directly to scope.

I'd like to be able to pass 'bla' as a string without the '', in the following way:

You would just need text binding (@) binding for that, instead of 2 way binding.

.directive('pTest', function() {
    return {
        scope: {
            something: '@?' //<-- Here
        },
        templateUrl: 'components/testTemplate.html',
        controller: 'testController'
    };
});

and with the text binding if you want to bind scope properties then use interpolation. i.e example if bla is a scope variable holding a string then just do:

 <p-test something="{{bla}}"></p-test>
