Though Google used namespaces incorrectly, Inkscape does not. And as
we've seen the use of Inkscape annotated SVG is not uncommon.

More importantly many SVG files also have properly used and namespaced
Creative Commons licenses. If we want to strip the Inkscape
annotation, we cannot strip the CC annotation.

But this is all stuff we knew and stuff we've been talking about.
That's why I'm not sanguine on the new ideas with namespaces in
separate files. I believe we need to make namespaces in HTML work
because we will have to deal with namespaces in HTML -- some members
of the HTML WG not liking namespaces and validators throwing out too
many errors and messages to be useful are not going to stop what is

As for Google's error, you know if the company doesn't care about the
quality of its web pages, that's the company's problem. I'm not going
to spend time helping a company that has the capability of putting out
valid web pages, but seems to be indifferent about doing so.
