My claim was that if you take an SVGT12 svg font and run it through an SVG  
1.1 validator it would conform to SVG 1.1. Therefore I could just as well  
have called them SVG 1.1 Fonts. I made no claim that they'd cover the  
whole set of functionality in SVG 1.1 however.

Sure, to the best of my knowledge there are no available products that  
support all of SVG 1.1 Fonts. The argument about incomplete  
implementations would probably be valid for many other specs/standards too.

I've not yet seen any evidence of there being any significant differences.

I'd like to see some data to back that claim.
