Although they are ugly, they did do one thing correct, and that was to
place the burden of namespace resolution and use on the final document
creator.  I think that namespace/prefix should be defined by the web page
designer and not the component library designer. This allows end users of
the component the ability to resolve the conflicts, instead of filing a bug
report and a component designer has to fix all namespace resolutions.

As a component designer, I'd like the ability to develop with a single
<panel> instead of <my-really-long-hopefully-not-conflicting-panel>.

I definitely prefer the prefix solution as it "looks" cleaner in the end
product.  document.registerElement should warn/error if the end product tag
is already in use, that's for sure.
