>From Marcos Caceres (marcos@marcosc.com) 

The following is not defined correctly:

[NoInterfaceObject]
interface NavigatorMIDIAccess {
    void getMIDIAccess (NavigatorMIDIAccessSuccessCallback successCallback,
optional NavigatorMIDIAccessErrorCallback? errorCallback);

};


Should just be:

partial interface Navigator {
    void getMIDIAccess (NavigatorMIDIAccessSuccessCallback successCallback,
optional NavigatorMIDIAccessErrorCallback? errorCallback);
};





Bikeshed: NavigatorMIDIAccessSuccessCallback is a little excessive :) Just
called them "successcb" and "failcb". They are just functions without a "real"
interface, so no need to go all camel case there :)

Also, MIDIPort should not be a [NoInterfaceObject]. Either fold it into
MIDIOutput or make it into a partial interface.

Generally speaking, don't make things [NoInterfaceObject]. WebIDL says not to
do that unless its for Legacy reasons:

[[
Warning

The [NoInterfaceObject] (http://www.w3.org/TR/WebIDL/#NoInterfaceObject)
extended attribute should not be used on interfaces that are not solely used as
supplemental (http://www.w3.org/TR/WebIDL/#dfn-supplemental-interface)
interfaces, unless there are clear Web compatibility reasons for doing so.
Specification authors who wish to use this feature are strongly advised to
discuss this on the public-script-coord@w3.org
(mailto:public-script-coord@w3.org) mailing list before proceeding.
]]

Also applied to MIDIEvent.
