The voting form G18 is mentioning the following:
If a national body votes affirmatively, it shall not submit comments. If a national body finds the DIS unacceptable, it shall vote negatively and state the technical reasons.
Microsoft is trying to take the voting rules as literally written in section 9.8 of the JTC1 directives:
Approval of the technical content of the DIS as presented (editorial or other comments may be appended);
and they are trying to argue that "other comments" can be technical comments.
Unfortunately, as stated in Australia Standards meeting, a vote of "Approval with technical comments" is like an "Approval with a Christmas card". No value, no any warranty that the serious problems that are in the specification will be solved anytime.
