MutationObserver API

A code example:

if (MutationObserver.is_supported()) then
  let doc = Dom_html.document in
  let target =
    Js.Opt.get (doc##getElementById (Js.string "observed"))
      (fun () -> assert false)
  in
  let node = (target :> Dom.node Js.t) in
  let f records observer =
    Firebug.console##debug records ;
    Firebug.console##debug observer
  in
  MutationObserver.observe ~node ~f
    ~attributes:true ~child_list:true ~character_data:true
    ()
