<P>Dear Sirs,<BR><BR>I appreciate your efforts to update ISO/IEC
14496-22<BR>for synchronization to OpenType 1.5. One of the
interesting<BR>feature of OpenType 1.5 for CJKV people is the
explicit<BR>support of Unicode Variation Sequences.<BR><BR>Yet I've not
checked in full, but now I have 3 questions<BR>on ISO/IEC 14496-22 2nd ed.
WD.<BR><BR>ISO/IEC 10646 and Unicode
references<BR>------------<WBR>---------<WBR>---------<WBR>------<BR><BR>After
ISO/IEC 10646:2003, there are 2 amendments,<BR>Amd.1:2005 and Amd.2:2006.
Unicode 5.0 claims it<BR>supports these 2 amendments, so, I think there's no
<BR>reason to exclude these amendments from the normative<BR>list, except an
editorial reason to avoid "too many<BR>references".<BR><BR>Speaking as a
person from Japan, Amd.1:2005 includes<BR>the update for Japanese industrial
standard of<BR>character set JIS X 0213:2004, so I wish if ISO/IEC<BR>10646
amendments are explicitly cited.<BR><BR>One of the remarkable feature of
OpenType 1.5 is<BR>variation sequence support by cmap format 14.<BR>Unicode
variation sequence is a part of Unicode,<BR>but there is more "normalized"
operation of UVS,<BR>Ideographic Variation Database (IVD)<BR><A
href="http://www.unicode.org/ivd/index.html">http://www.unicode.<WBR>org/ivd/index.<WBR>html</A><BR>IVD
is standardized by Unicode Technical Standard #37,<BR><A
href="http://www.unicode.org/reports/tr37/">http://www.unicode.<WBR>org/reports/<WBR>tr37/</A><BR>but
this is NOT a part of Unicode standard. So, I'm<BR>interested in if ISO/IEC
14496-22 will list it in<BR>Normative Reference, or not, or leave it to
OpenType<BR>specification maintainers.<BR><BR>version
number<BR>------------<WBR>--<BR>In the case of Open Font Format, there is an
idea of version<BR>number (except of the publishing date of ISO/IEC
14496-22)?<BR>If there is, ISO/IEC 14496-22:2007 is 1.0? Or, to
synchronize<BR>with OpenType v1.4, it should be 1.4? There might be 2
different<BR>ways of correction, I think.<BR><BR>correction a)<BR>remove the
sentence. Because OpenType 1.3 was never standardized<BR>as a part of ISO, so
it's reasonable to claim that there's no<BR>previous version of OFF before
ISO/IEC 14496-22:2007.<BR><BR>correction b)<BR>replace it as "OpenType 1.3" as
original OpenType 1.4 spec said.<BR><BR>OpenType layout feature
registry<BR>------------<WBR>---------<WBR>---------<WBR>--<BR><BR>On 14496-22
2nd WD p. 296-300 "5.4.3.1 Feature Tag List",<BR>there are 2 undescribed
tags.<BR><BR>In OpenType 1.4 & 1.5, "jp04" and "hojo" tags are
listed<BR>and described. In ISO/IEC 14496-22:2007, they are not<BR>listed and
not described. In 14496-22 2nd ed WD, they<BR>are listed but not described.
Personally, I wish if they<BR>are listed and described, but if there's
background<BR>reason to drop them in ISO/IEC 14496-22:2007 (and it's
not<BR>outdated), they should be dropped in the 2nd edition
either.<BR><BR>Regards,<BR>mpsuzuki<BR></P></DIV><!--End group email --></BLOCKQUOTE></BODY></HTML>
