EventHandler is defined at http://www.w3.org/html/wg/drafts/html/master/webappapis.html#eventhandler and equivalent in the WHATWG HTML spec.

I agree that the instances of EventHandler in the IDL in websocket API should link to that definition.  However, note that http://dev.w3.org/html5/websockets/#dependencies explicitly notes that a number of fundamental concepts from the HTML specification are used in this one, and EventHandler is one of those.  Just like EventTarget is actually coming from the DOM specification here.

I know that. But that definition is not referenced.

Any externally defined type needs to be explicitly linked or cited, not included in a general "fundamental concepts" clause.

Just use http://www.whatwg.org/html#network

The W3C version is only useful for patent policy purposes and is not guaranteed to have fully working cross-references, etc.

The W3C version is the only one that matters, and needs fixed. Please don't re-close until fixed or I will just re-open.

Taking off my radar.
