Does SVG offer any advantages over, say, EMF/WMF? I know a strong advantage of WMF is that the file format translates 1:1 into GDI calls, which makes it very fast - but I don't see EMF files rendered with anti-aliasing or complex gradients. What about PDF or PostScript?
Good SVG can even be human-readable and -editable. I've actually fixed simple broken SVGs with vim and a pocket calculator.
PostScript is great but as a binary format not very modern, where text-based formats seem preferred. I had to look up WMF and dumping calls to Microsoft API as an 'open' standards does not sound too exciting, either.
Its disadvantage is that it is a full on programming language, not declarative, so it isn't friendly to editing tools.
Sadly, programming is coming to SVG as well with more and more renderers supporting JavaScript. Which might be great for some use cases, but again even further disperses the field of possible generator/feature/renderer combinations that might (will) fail.
S... strong advantage?
