I've noticed that certain SVG features such as
@font-face w/ base-64 content and
fill styles do not seem to work with Illustrator. (SVG image not displaying CSS base-64 data URL encoded fonts in Illustrator)
Is there any documentation -- official or unofficial -- that explains which SVG features are supported by Adobe Illustrator? (both for exporting and importing)
In particular I'm working with SVG 1.1 and Illustrator CS5, but I'd be happy to see some info on any version. I've seen some "SVG enhancements" notes on Adobe's site, but nothing substantial.
