[UPDATE] I thought I’d give some graphs for the results of the ballot-changes of DIS 29500 mark II. These are the results as at Wednesday, and I think they are the finals. (There is one non-P NB whose vote I am not sure of: I have shown it as abstain though it could be accept.)
Here is a graph of all the votes case, showing the change from the initial ballot until now (as far as it is publicly known). This is based on all the NBs who voted. (However, this is not the count that is used to determine success…)

At ISO/IEC JTC1, national standards bodies (called NBs) nominate what kind of participation they are interested, for each of the multiple subject-oriented Steering Committees (SCs). They can nominate in two classes: Participating Members (P-members) are supposed to maintain an active interest, attend meetings, and vote on all the standard drafts that come up. Observing Members (O-members) can vote, but they don’t have any obligations to show up to SC meetings.

Here is the vote when you just look at the P members (as far as it is known.) Note that “abstain” votes have a very particular meaning in ISO: it does not mean “reject” or “protest”, it means that the voting body could not decide, or is happy let the consensus of other NBs determine. There is no shame or difficulty with an NB voting abstain. (At earlier stages of drafts, there are “No with comments” votes: these often are “conditional yes” votes, which can explain how a “reject” vote can become an “accept” vote. At the current stage, however, no means no.)

Finally, now we have seen the big picture, we come to the real numbers that count. There is a negative test and a positive test. First, no more than 1/4 of all NBs who vote can be negative (ignoring abstains). This has not been reached (i.e. not enough rejections: the all-nation acceptances are over 75% on the following graph.)

Then there is a positive test: at least 2/3 of all P members who vote should vote for acceptance (ignoring abstains again). This has been reached (i.e. enough acceptances: the P-nation acceptances are over 66.7% on this graph.)

So OOXML has been accepted, seemingly by 24 to 8, which is enough of a margin to avoid “hanging chad” clawback games.
It is clear that most NBs think DIS 29500 mark II makes a credible and acceptable or useful standard, but there is a substantial and active minority that does not.
Australia is continuing its abstention, and I think that is the correct vote under the circumstances, even though I personally support DIS 29500 mark II.
I am surprised more countries did not abstain.
