Section 3.1 says:
ASCCHAR = %x21-25 / %x27-7E / UNICHAR ; Note: AMPERSAND is %x26 UNICHAR = "&#x" 2*6HEXDIG ";"
It should say:
ASCCHAR = %x21-25 / %x27-7E / UNICHAR ; Note: AMPERSAND is %x26 UNICHAR = %x26.23.78 2*6HEXDIG ";" ; starts with "&#x"
It has to be a lower case "x", i.e. %x78 in RFC 5234 ABNF.
(All quoted strings in ABNF are case-insensitive.)
