I'm aware of that, that's why I said that my R-b would stand
whether or not you decide to address these points.

That said, I'd really prefer it if we started being more
to the point with our test data and really only include the
relevant information rather than copy the same pointless
bits over and over again.

Here's a counter-offer: if you agree to follow my advice
above and use a minimal input file, I'll post a patch that
strips the other qemu-ns*.xml from unnecessary cruft. Does
that sound fair? :)

Hence proving that the alternative syntax and the canonical
one result in the same output file. Why wouldn't we want to
test that?
