I'm willing to forgive all these format's sins simply because I spent so much time in the eighties and early nineties dealing with all the retched and poorly documented bespoke formats people came up with before these existed. It was a breath of fresh air to be able to tell customers their XML file doesn't validate hence it is their problem not mine.
