[idn] Requirements: sorting

[Paul Hoffman / IMC <phoffman@imc.org>]

In the second paragraph of section 2.4, it says:

>The DNS has to match a domain name in a request with a domain name held
>in one or more zones. It also needs to sort names into order. It is
>expected that some sort of canonicalisation algorithm will be used as
>the first step of this process. This section discusses some of the
>properties which will be required of that algorithm.

I couldn't find any requirement in RFC 1034 or RFC 1035 that required 
sorting by names. Is this requirement in any other DNS standard? If not, I 
strongly suggest we remove the second sentence of this paragraph, since 
sort is incredibly problematic in internationalization.
