Set object identity identifier

[r3m4k3]

I want to set the object identity identifier for class permission.
Now it's set from ACE identifier. It would be great to set ACE as ObjectIdentity.

My solution is - create an empty object and with setter and as id set my own string name.

$tmp = new Page();
$page->setId('literal_name');

Is there any solution? This one is not an elegant one. :/
