In Part I of this OOXML update, my first post on the topic in over a year, I showed you how Microsoft maintains strong control over the OOXML standard.

everal months ago, thanks to the SFLC it was shown that OOXML is not suitable for implementation by Microsoft’s #1 competitor.

In all my years working as a journalist, I've never seen any technology company spin information the way Microsoft did today. The press release on OOXML ratification is a blueprint for spinning semantics, and the stringing together of truths and half-truths to seemingly make the outcome of one event something else altogether.
