You mean Open Document Format! D'oh!

As to the independence of this particular report, that's irrelevant - anyone applying intelligent thought to the matter cannot avoid the obvious: "MS Open Office XML" is NOT an open standard, by any stretch of the imagination. To claim otherwise is laughable. Even the name smacks of desperation - no less than the BSI states that it is deliberately designed to create confusion with ODF and its name should be changed (as well as that the format should be redesigned from the ground up, based on ODF).

Let us not forget that ODF is already an approved ISO standard, and that however much Microsoft moans about it not having the correct features to support Windows applications, the glaring irony is that Microsoft was always at liberty to take part in its formulation and standardisation process, yet refused, and (as the standard evolves) still refuses to do so.
