you're right. You could even use curves, arcs, cubic or quadratic beziers or
elliptical arcs within path elements - http://www.w3.org/TR/SVG/paths.html
for the whole story ...

well, definitly - the papers at http://www.svgopen.org/ and you'll
show a lot more ;-)

if you're referring to GeometryN(geometry,int) or InteriorRingN(geometry,integer)
or similar OpenGIS functions - PostGIS can do that, the only thing left to do
from the SVG point of view is to deliver results as simple M's or maybe cx,cy ;-)

any comments on my last question? not implementing the whole thing, just
