HTMLCollection object extensions?

Question

I found that HTMLOptionsCollection object inherits properties and methods from HTMLCollection.

HTMLOptionsCollections->HTMLCollection->Object->null

Is there any other type that also inherits HTMLCollection?

Answer 1

You'll find other DOM interfaces which should inherit from HTMLCollection in the HTML5 spec:

However, these objects are not necessarly actually implemented in current browsers.
