RE: [xri] First cut at new BNF

["Wachob, Gabe" <gwachob@visa.com>]

Dave-
	I ran the abnf through http://www.apps.ietf.org/abnf.html and got a couple of errors:

unreferenced rule: ipath-noscheme
unreferenced rule: xri-characters
unreferenced rule: reserved
unreferenced rule: XRI
ABNF validation (version 1.0) completed

	Seems like XRI is not a problem. Don't know about the others. 

	Do you know of any tools that allow you to "play around" with BNF's? This one is getting beyond a mere mortal's ability to follow...

	-Gabe
