Re: It's free....
Wasn't the ooxml standard the one that Microsoft was pushing so that it could comply with European requirements that documents be saved in a standard format.
I can't understand your logic on why open/libre office wont work with Microsoft formats. Microsoft is the dominant player, a big argument for not using open/libre office is because of the lack of interoperability with everyone else using Office and the legacy of office documents laying around that is only compatible with MS products.
There is absolutely no reason why libre/open office devs wouldn't want their product to work with Microsofts.
On the flip side there are some very solid reasons that Microsoft wouldn't want competitors to be able to work with their products.
There is a good quote from wikipedia
If ISO were to give OOXML with its 6546 pages the same level of review that other standards have seen, it would take 18 years (6576 days for 6546 pages) to achieve comparable levels of review to the existing ODF standard (871 days for 867 pages) which achieves the same purpose and is thus a good comparison.
Considering that OOXML has only received about 5.5% of the review that comparable standards have undergone, reports about inconsistencies, contradictions and missing information are hardly surprising
If MS simply said that the format is closed and will not be made available, I would be fine with that.
The fact is that they forced a standard through ISO so that they could pretend to governments and organisations that their formats were based on open standards and that they wouldn't locked into a single vendor for ever.
