Rails 3 How can I allow nested attributes to be passed without the _attributes designation

Question

When using accepts_nested_attributes_for, instead of having to pass "child_attributes", I'd like to pass "child". I'm pretty sure if I put a lot of the logic in my controller to create the the records and children, I could accomplish this. However, in an effort to keep my controllers clean and logic where it should be, the model in this case, I'd like to know how to switch rails 3 around to use this syntax when doing a POST or PUT.

{
  "name": "test",
  "child_attributes": [
    {
      "id": 1,
      "name": "test_child_update"
    },
    {
      "name": "test_child_create"
    }
}

Rather

{
  "name": "test",
  "child": [
    {
      "id": 1,
      "name": "test_child_update"
    },
    {
      "name": "test_child_create"
    }
}

Evidently, this can't be done.
