That's what the spec has right now, but it calls them DOMRectReadOnly and DOMRect (since the mutable one has a constructor, it's nicer for it to have a short name). The two interfaces now have their top/right/bottom/left attributes identical. We could move them to a common interface, like DOMRectBase or AbstractDOMRect. -- Simon Pieters Opera Software
