Of course we should allow for trailing combining marks. <br><br>The reason that the trailing combining marks were forbidden earlier was because of the defective IDNA2003 bidi restrictions, which allowed labels that shouldn't have been allowed, and disallowed labels that should have been. So I was including both that under the phrase "better". The latter part is also covered by the next bullet (about effective use).<br>
<br>So I don't think we need the bullet about "mnemonics" -- it just confuses the issue.<br><br>Mark<br><br><div class="gmail_quote">On Wed, Feb 27, 2008 at 12:18 PM, John C Klensin <<a href="mailto:klensin@jck.com">klensin@jck.com</a>> wrote:<br>

I assume that the "additional mnemonics" text was intended to<br>
permit the modifications that started the IDNA bidi discussions,<br>
i.e., to permit trailing combining marks so as to make mnemonics<br>
based on Dhivehi, a larger number of mnemonics based on Yiddish,<br>
etc., possible. If the work were confined to "visual<br>
disambiguation", as you seem to suggest above, that change would<br>
be excluded. Is that what you have in mind?<br>
