Are you suggesting that a document format should be a monolithic controlled by one organization and is actually more open than one that allows multiple entities to contribute to an artifact without permission or coordination? You can think that if you want, but you have to actually argue for it, not just assert it, because to me, that's closed, not open.

Or is it that you just really hate UUIDs? Me too, man. Should have gone with reverse DNS. It's a technical and aesthetic quibble though.
