Yes, unfortunately, W3C still seems determined to hold to the fiction that 
it's too hard to fix SVG so that any possible dependency on Apple's (probably 
bogus) patent is eliminated.  It is apparently much easier for W3C to help 
Apple patent the standard, which is the situtation as it stands now.

SVG is patented guys, make no mistake about it.  It is patented because W3C 
is too weak-kneed to do anything about it.
