Ballot on PDAM 5 of UCS
The National Body of Japan disapproves the ISO/IEC PDAM no.5 to
ISO/IEC 10646-1 (ISO/IEC JTC1/SC2 N2575, ISO/IEC JTC1/SC2/WG2
N1209) with the following comments.
----- Comments regarding Procedures and General Principle-----
Comment Number:G-1
Qualifier: Procedural
Comment:NP approval or approval of subdivision of existing
project is necessary
Rationale:This is substantive change on existing International
Standard (Refer to Seoul meeting minutes, same proposal
has been rejected because this is substantive change)
Proposed Solution:At least simultaneous letter ballot with PDAM
document is necessary, the simultaneous ballot does not
cause any delay of the PDAM provision.
Comment Number:G-2
Qualifier:Principle
Comment:Even though additional characters has different name from
existing Hangul, reality is nothing more than duplicated
coding. Avoid duplicated coding.
Rationale: Duplicated coding should not be allowed in ISO/IEC
10646
Proposed Solution:Do not add Hangul syllables that are already in
ISO/IEC 10646-1
Comment Number:G-3
Qualifier:Principle
Clause: Section B
Comment:Removal of characters out from existing code table shall
not be done.
Proposed Solution:Do not add Hangul syllables that are already in
ISO/IEC 10646-1, and do withdraw Section B of PDAM no.5
to ISO/IEC 10646-1
Comment Number:G-4
Qualifier:Principle
Comment:Ordering reason for the duplicated coding is not
acceptable
Rationale:The character mapping principle of ISO/IEC 10646-1 is
independent from ordering of characters in it.
Proposed Solution:Do not add Hangul syllables that are already in
ISO/IEC 10646-1.
Comment Number:G-5
Qualifier:Principle
Comment:Do not change character names as a reality. Even though
it looks like adding new characters and deleting
existing characters (which have different names), reality
is nothing more than change of character names.
Rationale:Character names shall not be changed
Proposed Solution:Do not add Hangul syllables that are already in
ISO/IEC 10646-1
-------Comment regarding Implication of this PDAM--------
Comment Number: I-1
Qualifier:Implication review
Comment:This PDAM has a possibility of inhibiting future addition
of repertoire to BMP. The addition of such a large
characters has to be approved after review with all other
repertoire addition requests.
Rationale:This PDAM and Reservation of O-zone space for future
needs (SC2WG2 N1140) occupy all of O-zone space. There
will be NO O-zone SPACE AVAILABLE FOR CHARACTER ADDITION,
this means no large code space available within BMP until
Section B of PDAM no.5 is effective. On the other hand,
SC2WG2 N1178,1179 indicate a requirement of large code
space for CJK characters. In addition to that, SC2WG2
N1241 lists many other requirements of characters such as
2000 ea. of Indo-European, 220 ea. of Byzantine musical
symbols, Tibetan, Mongolian,Yi and so on. It is better to
review all of those requirements before prohibiting them
to be mapped in BMP by accident.
Proposed Solution:Priority review is necessary, and consider to
map PDAM no,5 characters on to other than BMP if it is
necessary.
-----------------Technical comments--------------
Comment Number: T-1
Qualifier: Technical
Clause:Section A, Page 8, Clause 12
Comment:Reasoning of this amendment is not acceptable
Proposed Solution:Delete all text
Rationale:This reasoning does not justify this amendment at all.
If this practice is accepted, then other countries may
make major revisionof National Standard every time their
request for ISO/IEC 10646 is rejected (revision shortly
after publication of International Standard like this
case, in particular, should be avoided) leave room for
future amendment for other reason(s).
Comment Number:T-2
Qualifier:Technical
Clause:Section A, Page 12, Clause 19
Section A, Page 15, figure 3
Section A, Page 700, Annex A
Section A, Page 709, Annex E
Section B, Page 12, Clause 19
Section B, Page 15, figure 3
Section B, Page 700, Annex A
Section B, Page 709, Annex E
Comment:Block name shall not be changed
Proposed Solution:Leave current block name as it is, and assign
new block name for additional Hangul.
Rationale:Block name may be already used for SELECTED SUBSETTING
and other purposes. In principle, block name should be
handled as same as character names in term of changing.
Comment Number:T-3
Qualifier:Technical
Clause:Section C
Comment:Character name in sample page is not acceptable
Proposed Solution:Add annotation onto each character.
Rationale:The character name in Section C is per ISO CD
11941.3. (Transliteration of Korean script (Hanguel) into
Latin characters, Document number ISO TC46/SC2 N335).
The CD ballot was failed, and resolved to publish
Technical Report.
The TR is not published yet, but it was agreed that the
TR will include two transliteration proposals. It is
not wise thing to use the rejected proposal as it is in
another ISO/IEC standard. As a compromise (like wise TR
mentioned above), It would be better to add another
transliteration as an annotation.(If ISO/IEC JTC1 SC2 WG2
believes that even two names might invite political
difficulty, it would be better to use new naming
independent from ISO CD 11941 discussions)
Comment Number:T-4
Qualifier:Technical
Clause:not on the PDAM
Comment:Add new normative annex to show relation between existing
Hangul and new added Hangul
Rationale:For easy migration, it is necessary to add normative
annex which describes mapping between existing Hangul and
added Hangul.
Comment Number:T-5
Qualifier:Technical
Clause:not on the PDAM
Comment:Add new informative annex for conversion tool from
current ISO/IEC 10646-1 to new ISO/IEC 10646-1.
Rationale:While SC2 WG2 meeting #27 in Geneva, it was committed
to provide "conversion tool" for relieving existing
implementation in new coding. Since the conversion is not
easy business, it is not possible to accept the proposal
without reviewing the proposed conversion tool(s).
Remember that simple conversion table normally does not
work enough. If the tool does not fit (informative)
annex, then separated contribution document(s) must be
provided for this pdam review.
----------Editorial comments---------
Comment Number:E-1
Qualifier:Significant editorial
Clause:Section A, page 15, figure 3
Comment:Instead of wording, provide real figure 5 for review
before voting
Rationale:Impact of this amendment on code space allocation on
over all ISO/IEC 10646-1 should be much clearer for all
reviewers of this amendment.
Comment Number:E-2
Qualifier:Minor editorial
Clause:Section A, Page 751, Annex L
Comment:Korea to be Korean
Remarks:This might be handled as a part of COR already
Comment Number:E-3
Qualifier:Significant editorial
Clause:Section C
Comment:Final proposed table should be provided for review before
voting
Rationale:SC2WG2 has experienced many mistakes on edition of
tables in the past. It is necessary to review full real
page of table before voting approval or disapproval.
