OOXML needs to die. It's clear that OOXML is a faux standard -- not because it's a vendor standard. There are lots of vendor-created standards which are real standards (e.g. PostScript). No, OOXML is a botch because it's expressed in terms of an undocumented Microsoft graphics library. OOXML is all "and then a miracle occurs". You've seen that cartoon, right?
The OSI adopted a mandate of working on Open Standards two years ago. We put forward a statement on requirements for an Open Standard which boiled down to a simple proposition: if the standard could not be implemented fully and faithfully in Open Source, the standard should never be declared nor considered open.
