SVG is a pretty good example because (some) browsers _do_ support the
SVG "semantics" (in the sense that they understand when to draw a
circle, when to draw a path, etc.). I think a lot of people who are
complaining at the moment might be happy if there was a possibly to do:
<!-- SVG content here -->
And similarly with say, MathML. I don't think there's anything desirable
about calling the attribute xmlns because the semantics would differ
from that attribute (it would only allow namespaces on a per-subtree basis).
I don't pretend to know how parsing would work though.
