No, but SVG is XML, and thus it has. You can embed hyperlinks in SVG by
using the xlink namespace -- firefox even honours that. And you embed
SVG in html5, which isn't XML (we nearly had that, btw). That's the result
of that consortium thing: they prefer to continue their "fuzzy parser
wars". Gotta live with that.

Yep. SVG /is/ XML, for better or worse :-)

Yep [1]. "Interesting" is a polite way to put it. My take would rather
be "@%#$&*!", but then, I was born in Spain, and some of us are said
to have bad language ;-)

My point is that those "norms" are built to leave bigcorps enough
wiggle room to try to dominate the market by bending them. Otherwise
the "norms" wouldn't be relevant in the first place.

OTOH, no norms would be even worse. But one shouldn't be too naive
to believe what's on the box. Just look inside :-)
