In particular the spec states that key paths are DOMStrings, and then goes on to state how Array key paths are handled. Whatever changes are made need to preserve the note about key paths not nesting just after 4.7.1.
Definately seconded. We've had some misunderstandings because of this. You can give an array of keyPaths both consumers, but IDBObjectStoreParameters is totally lying straight to our face by saying "DOMString?". IDBObjectStore.createIndex IDL is "any keyPath", which is correct. It may even be clearer to write (DOMString? keyPath or DOMString[] keyPath) or do an overload. You'd have to ask someone who knows WebIDL better :-)
You are supposed to give keyPaths as arrays, they can be very useful. It will build a new array of the values it found from each of the keyPaths that's used as a key. They won't disappear, they exist in all IDB implementations - the unclarity stems from the spec.
