Re: Internationalised/Localised postal code and country elements

Hi Gavin,

I actually had the same thought as you do, but I'm not sure if "loc" and "int" would be the same...

pc and cc are defined as:

 <simpleType name="ccType">
      <restriction base="token">
        <length value="2"/>
      </restriction>
    </simpleType>

    <simpleType name="pcType">
      <restriction base="token">
        <maxLength value="16"/>
      </restriction>
    </simpleType>


So technically a postal code can be provided in any script as well as the country code as long as the length value is met.

Folks that communicate in writing using non ascii characters would find that useful.

regards,

Since both of these fields consist solely of ASCII text (my research suggests that internationally, postal codes are solely alphanumeric), i cant see any benefit to allowing this, and I can conceive of a scenario where such a difference could cause operational or security problems (eg an abusive or malfunctioning domain appears to be registered in different territories, depending on the I18N preferences of a WHOIS client).
