I am horrified by what Microsoft is doing to the world with the introduction of their suspiciously ISO fast-tracked bad designed OOXML formats, that made ISO not independent anymore as it seems ISO has been bought by Microsoft.
There is already the great OpenDocument format that conforms to other ISO standards.
I think Google expressed very well the problem with OOXML. But anyway OOXML is not even harmonic itself.
Now, that ISO made clear that their standards are not serious. The effort would be either to stop the corruption inside ISO or made international governments either audit ISO or stop accepting ISO standards and move to a fairer organization that maintains standards. At NoOOXML there is much more information about this issue.
OOXML is just an excuse for Microsoft to break the document format again and force users to upgrade. I am sure they could not care less about standards and collaboration.
