I agree completely, Tab, but it's actually too late to stop forcing authors
to think about namespaces, the fact I currently have to think about it is
the source of this suggestion.

The merging of namespaces is the ideal solution, no doubt, but it's
probably not a realistic solution in the short or even medium term. It's
almost the equivalent of punting.  SVG and HTML differ too drastically to
just combine them overnight, I suspect. Different types stored in
properties, different APIs, etc.

It would be far easier/quicker to add an attribute and deprecate it later
than get the namespaces merged. At the very least, it would immediately
provide authors something they could polyfill to solve this issue.
