SHOULD).  Though they may make linguistic sense, and seem sensible, I’m not
sure what value they provide.  I can see that they address perceived “bad” or
unreasonable cases, and their restrictions may aid perceived security.  (Although
you point out they can be ignored)<o:p></o:p></span></p>

rules address security at all.  IE’s anti-phishing and malicious web site code
really has pretty much nothing to do with IDN, and it’d probably catch abusive web
sites anyway.  (IE does script-detection, but it’s looking at the Unicode
string, not a specifically IDN string.  The other techniques are more general
and protect against ASCII-only URLs as well)<o:p></o:p></span></p>
