Hi, Just to clarify the suggestion to have complete RBNF grammar at a living document was just for informational purposes (and not to bypass the IETF process). It stemmed from trying a different approach than the one already attempted in the past.
I am all for trying the approach suggested by John and Robert. <snip> > > Exactly.
