I think the SVG-WG should consider <replicate> for SVG 2.0 since there
seems to be a bunch of useful things it could be used for.

Indeed. One of the earliest demos I did with my CDF engine had SVG Fonts
pulled in for rendering the HTML text, then when I demo'd it to the
SVG WG back in early 2007, Cameron (McC) asked if the animation could
apply to the HTML markup? I edited the markup placing the <animate>
elements in the SVG namespace and targeted the color of the HTML text
and lo and behold it just worked(tm).

So a clean model should easily handle <animate> on any node in a DOM
tree given this is all unified in one code base in all browsers these
days. And this would naturally extend to things like <replicate>
as well.

Cheers,
Alex
