<p class=MsoNormal>John, Harald,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>A few observations on the integration of BIDI into the
protocol document.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In the draft-ietf-idnabis-protocol-14 document Section
4.2.3.4:<o:p></o:p></p>
<p class=MsoNormal>If the proposed label contains any characters that are
written from right to left it MUST meet the "bidi" criteria
[IDNA2008-BIDI].<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The above implies that the label must meet the BIDI
criteria, however BIDI criteria is applied to a BIDI domain name. From
draft-ietf-idnabis-bidi-04, “The following test has been developed for
labels in BIDI domain names” and “A "Bidi domain name" is
a domain name that contains at least one RTL label”. I hesitate to
provide alternative text for until the following question has been answered.<sub><o:p></o:p></sub></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The protocol states that the proposed label contains any
characters written from right to left it MUST meet the bidi criteria. It
does not impose such requirements on labels containing no right to left
characters. Consider the registration of label ‘123abc’ in a
zone containing labels written right to left. The label does not contain
any right to left characters, therefore does not have to meet the BIDI
criteria. However this name is a BIDI domain name, yet such a name would
fail as the first label (LTR) does not begin with BIDI property L. Is the
label intended to be valid for registration given a right to left zone?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I note also the inconsistent use of the term BIDI. In
draft-ietf-idnabis-protocol-14 section 4.2.3.4. it is quoted and in lower-case,
whereas the draft-ietf-idnabis-bidi-04 uses the upper-case version
extensively. Also, within draft-ietf-idnabis-bidi-04 the term "Bidi
domain name" in Section 1.4 is inconsistent with “BIDI domain
names” in Section 2, and the tem “Bidi rule” in Section 10 is
inconsistent with the several other occurrences in the document.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
