Let's make it a goal that the XML we output is pretty. That clearly was never a goal for the Suunto XML, but we can be oh-so-much-better than that. I still don't love XML, but let's try to make the best of a bad situation, and take pride in what we do. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
