Prior to the September 2 vote by the ISO, I should have posted this link to other articles about OOXML:
An "OOXML is a bad idea" blog entry compendium

However, as things turned out, Microsoft lost its bid. In addition to allegations of ballot stuffing in the USA, Sweden invalidated its vote due to double voting by a committee member:
Sweden's SIS Declares OOXML Vote Invalid - Will Change Vote from Yes to Abstain - Updated

The US committeee INCITS voted in favor:
INCITS confirms: U.S. to vote for Open XML in ISO

The ISO official press release says:
Vote closes on draft ISO/IEC DIS 29500 standard

A ballot on whether to publish the draft standard ISO/IEC DIS 29500, Information technology – Office Open XML file formats, as an International Standard by ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) has not achieved the required number of votes for approval.

Microsoft is now faced with the task of addressing numerous comments made during the procedures each ISO member followed in its internal balloting, in preparation for a Ballot Resolution Meeting to be held in February 2008. The decision of that meeting is final.
