[WebIDL] NoInterfaceObject and access to constants

Hi all,

I am trying to provide access to constants defined in IndexedDB interfaces. For example:
interface IDBRequest : EventTarget {
    void abort ();
    const unsigned short INITIAL = 0;
    const unsigned short LOADING = 1;
    const unsigned short DONE = 2;
    readonly attribute unsigned short readyState;
             attribute Function       onsuccess;
             attribute Function       onerror;
};
Given that this interface doesn't contain the modifier [NoInterfaceObject], shouldn't it be possible to access the global object, e.g., window and from that the interface and from that the constant? As an example:

window.IDBRequest.INITIAL or IDBRequest.INITIAL

For interfaces that should not be available as a property on the global object, I need to apply the [NoInterfaceObject] modifier, but that doesn't apply here.

Can anyone confirm or refute this so that an open issue on the IndexedDB spec can be closed without action?

Thanks,
Nikunj
