The European Commission DG Antitrust has started new investigations on whether Microsoft is abusing its dominant position on the Office market.
Here is what their today's press release "Antitrust: Commission initiates formal investigations against Microsoft in two cases of suspected abuse of dominant market position" is saying about OOXML:
The Commission's examination will therefore focus on all these areas, including the question whether Microsoft's new file format Office Open XML, as implemented in Office, is sufficiently interoperable with competitors' products.
Let's hope the Commission will be quicker to act then the previous case that lasted 10 years and was trumped by Microsoft's software patents.
Maybe Nellie Kroes could send a letter to Microsoft asking whether or not Office 2007 is compliant with ECMA-376, so that an AutoSpaceLikeWord95 can defeat the question of "sufficient interoperability".
