Thanks for the detailed (as always!) explanation. It sounds like ODF 1.2 is the way to go. My main concern was Office 2007 - I know that some segments of the user base stick with old versions of MS Office for a regrettably long period of time. But given it’s age and the nature of our project, I think it make sense to target 1.2 as the only output version. We can always revisit this later if needed.
