Created attachment 647250 [details] [diff] [review] v1 Running against Try Server now.
Adding add-on compat and dev-doc flags so that we document this when it lands.
How'd the try server run go?
Sorry I didn't respond to this at the time! I thought I had. The Try Server results were lost when (at some point) the whole Try Server system had to be restarted (around the time of comment 1, there were some Try Server Troubles). I just pushed to try again, not noticing that we're perma-orange on Mac right now--but the results on the other platforms will still be useful: https://tbpl.mozilla.org/?tree=Try&rev=9653a0823eb5
Created attachment 655395 [details] [diff] [review] v2 Ah, there was a new test that mentioned XML. Easily patched.
Was already mentioned at https://developer.mozilla.org/en-US/docs/Firefox_17_for_developers Made the message in https://developer.mozilla.org/en-US/docs/E4X a little bit more clear.
