That page describes gecko-specific aspects of IDL, so usually does not 
need to be updated for spec changes.


That said, it looks like it was never updated for 
https://bugzilla.mozilla.org/show_bug.cgi?id=1489301 (removal of 
[Exposed=System]).  I'll fix that now.

Is the page “WebIDL bindings” up to date as well? I often find it useful
too.

It was only a small mention.

I also removed the separate mention of the default value:

"If no annotation is available, the default value is Window."

I've removed the mention of PrimaryGlobal from
https://developer.mozilla.org/en-US/docs/MDN/Contribute/Howto/Write_an_API_reference/Information_contained_in_a_WebIDL_file.
It was only a small mention.

I also removed the separate mention of the default value:

"If no annotation is available, the default value is Window."

Web IDL interfaces now require explicit [Exposed] annotations

[Boris Zbarsky]

Starting today (on autoland,coming to m-c soon), there is no more 
[PrimaryGlobal] extended attribute on interfaces in our Web IDL, and 
therefore all interfaces need an explicit [Exposed] annotation saying 
where they are exposed (e.g. [Exposed=Window] for the case that used to 
not have any annotation and default-exposed on mainthread).


This aligns with upstream spec changes.

If someone forgets to add [Exposed] on your interface, the parser will 
helpfully complain that there are globals the interface could be exposed 
on, but it's not exposed on any of them.


Just copy/pasting IDL from specs should generally work; I believe most, 
if not all, specs updated to this upstream change a while ago.
