Stream attachment should open in new window

I'm using the code below to publish some link to a fan page:

$facebook->api (
    '/PAGE_ID/feed',
    'post',
    Array (
        'message' => '',
        'picture' => 'http://www.example.com/image.jpg',
        'link' => 'http://www.example.com/some/page.html',
        'name' => 'Some title'
    )
);

It works. The only problem is that if you click on the generated link on the fan page's wall (or in your stream) the page will open in the same window. I'd like fo开发者_高级运维r it to open in a new window.

I've searched the documentation but no mention of any parameter that would toggle this setting.

After some more research and judging by the comments on my question, this can't be controlled.
