IBM and Microsoft's OpenXML: Update

I'm impressed: IBM has just stuck a dirty great clog in the engine of Microsoft's machinations to get its Office XML format adopted as a formal standard:

IBM voted NO today in ECMA on approval for Microsoft’s Open XML spec.

Heavy stuff: I think we expect some horse heads to start turning up soon.... (Via C|net.)

Correction: further to Bob's comment, I've gone to the ECMA site and found the press release announcing the approval of the standard. Naively, I thought that somebody voting against it would block it: not so. Apologies for my over-enthusiastic analysis. I suppose IBM's move was therefore more symbolic than anything. Ah well.
