Regarding the IDNA200X bidi spec, the 4th rule in section 4 says "If an L is present, no R, AL or AN may be present." http://www.ietf.org/internet-drafts/draft-alvestrand-idna-bidi-03.txt However, the 1st rule says "Only characters with the BIDI properties L, R, AL, EN, ES, BN, ON and NSM are allowed." Should AN be added to the 1st rule? Erik
