So, which part do you miss? :) Seriously, perhaps formatting
could be improved or something. I'm always listening. And,
frankly, I don't like the crm representation that much either,
but couldn't think of any better way at the time. Still, what it
makes it great for me is that I don't have to stare like a sheep
at XML, it always gives me headache.
