Section 5 says:
url-resp-text = 1*(%x01-09 / %x0B-0C / %x0E-5B / %x5D-FE) ; Any TEXT-CHAR except "]"
It should say:
url-resp-text = 1*(%x01-09 / %x0B-0C / %x0E-5C / %x5E-FE) ; Any TEXT-CHAR except "]"
The skipped character %x5C is "\" not "]". I think the intent is to omit "]" since url-resp-text is used exclusively inside a [BADURL url-resp-text] response code, and they want to avoid aliasing the closing "]".
