Subject: RE: [xri] First cut at new BNF
Thanks Gabe. I just did this in my head so it's great that you ran it through a validation tool. The XRI production is fine as unreferenced. The reserved production is included in IRI even though it's not used, mostly so they could talk about it. I included it for the same reason. I've removed ipath-noscheme and xri-characters. No idea about a tool for playing around with ABNF, but I'm sure someone will have a suggestion.
