Greetings again. This version of the document (hopefully) addresses the issues that Erik Nordmark, our Area Director, brought up after the WG last call. It clarifies some of the topics that we in the Working Group didn't notice were not covered well, and there is much more overview material in the document.
There is one significant technical change in the document: it now specifies how to break up a domain name into labels. Earlier drafts said that this had to be done before using ToASCII and ToUnicode, but didn't say how to do it. IDNA now lists the full-stop characters that are used to break up a name. --Paul Hoffman, Director --Internet Mail Consortium
