WWWW.w3.org? Classy. Did all those interoperable implementations happily
use the "wwww.w3.org" namespace URI, following the examples in the SVG
spec? Did anyone notice it wasn't "www.w3.org"? Are they interoperating
in a way that actually uses the URI, or could a # be added in with
nothing breaking?

I see that namespace shows up in
http://www.svgopen.org/2004/papers/G-XMLAndSVG/ too. Also in
http://mapserver.gis.umn.edu/docs/howto/svg-howto and presumably
elsewhere in the SVG specs, including  http://www.w3.org/TR/SVG/coords.html
