Grumble. It would have been nice had he seen fit to share this result. AFAIK
he did not. OTOH, if he managed to miss obvious usage...

Yes, and it is also used, amusingly enough, in a bunch of specifications that
didn't bother to reference 2234. It seems the 9% usage of ABNF in RFCs figure
is likely a bit low...

Anyway, I've updated the writeup with information about this feature. I elected
to use SIP and I added IPP (2565), which also uses it.

Is there anything else I need to add?
