Looks good so far.  I think you should point out that arbitrary
percent signs are not allowed:  "%%%" is not an XRI.  Here's
some ABNF for XRIs:

xri = *xri-char

xri-char = %x1-24 / "%" 2HEXDIG / %x26-D7FF / %xE000-FFFD /
	%x10000-1FFFD / %x20000-2FFFD / %x30000-3FFFD / %x40000-4FFFD /
	%x50000-5FFFD / %x60000-6FFFD / %x70000-7FFFD / %x80000-8FFFD /
	%x90000-1FFFD / %xA0000-AFFFD / %xB0000-BFFFD / %xC0000-CFFFD /
	%xD0000-DFFFD / %xE0000-EFFFD / %xF0000-FFFFD / %x100000-10FFFD

HEXDIG = %x30-39 / %x41-46 / %x61-66
