<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>So are you suggesting that these “registration-only” context
rules instead be recommendations instead of MUST? <o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Frankly, I can’t get excited about them either way (MUST or
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>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>From the client point of view I don’t really think the context 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>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";

someone can answer.<o:p></o:p></span></p>
