For what it's worth, it's a requirement for us to be able to use
namespaces of some sorts since we're planning on implementing XUL
using XBL2. There are however multiple ways we can do this and I'll
need to look into which approach XUL developers prefer.

I'm also not sure that we can do without <style> and <script>, but we
can always add those as an extension to our implementation.

In general I would have appreciated at least being pinged about our
requirements before these changes had been made. In the current state
its unlikely that we'll be following the specification without
