These particular interfaces are no longer built as part of WebKit. They have never been completed. You'll need to use the interfaces in DOMCore.idl and the other DOM*.idl files instead. We hope one day to transition to te IGEN_DOM* interfaces (and at the same time remove the "GEN_" parts of their names).

That's because we don't support creating these objects via CoCreateInstance.

You can retrieve DOM objects from IWebFrame (e.g., IWebFrame::DOMDocument). That's the main way to access them.
