They are still part of Rust, just behind a flag. The reference currently does document unstable things as well. We haven't quite figured out the way we want to handle this kind of thing, generally. |

There was a problem hiding this comment.
I'd snip everything below this. You can move the comment into the Unstable Book, or it's in the git history. This also involves removing the link from the text above.

It's misleading to keep XID_Start and XID_Continue on the reference, since they may never be supported in stable.
