This exchanges has been very helpful in outlining what I think are two views and maybe even a compromise position for the WG to consider.<br><br>Plainly we have agreed that mapping should be available to ease the introduction of IDNA2008. We have also agreed that the canonical forms of IDN labels (U-label and A-label that are equivalent under the punycode and reverse-punycode mappings) are extremely valuable fixed points in the protocol.<br>
<br>The dialogue among Paul Hoffman, Andrew Sullivan, Pete Resnick and Patrik Faltstrom suggests to me that a definition of Mapping (prior to lookup) should be undertaken by the WG but that its use might be determined by application context. If that compromise is adopted, the Mapping would be recommended in cases where IDNA2003 compatibility is desired/needed but that mapping on lookup is not absolutely required under all circumstances. <br>
<br>If we take that path, it will be very helpful to have not only the definition of the mapping but also advice about conditions underwhich it seems strongly advisable to apply. <br><br>vint<br><br><div><span class="gmail_quote">On 4/14/09, <b class="gmail_sendername">Andrew Sullivan</b> <<a href="mailto:ajs@shinkuro.com">ajs@shinkuro.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
