Links in these generated API skeletons use domxref so they can be used in the official location as well as this developer location or other users'. As a consequence clicking any links will get you to the official docs. A red link means there is no such official document yet. This should be quite useful in assessing how many pages are missing. See the Apps API interfaces (
DOMApplication), where a lot is missing. The tags at the bottom of any API documents will also find these developer pages, just look for User:maybe/webidl_mdn.
