Re: Minutes, 22 April 2010 SVG WG meweting

Hi, Dr. Olaf-

I think it would be a good idea to get rather more precise on these 
points in SVG 2.0.  For SVG 1.1 SE, I personally want to simply finish 
it, and work with browser vendors, other implementers, and folks like 
you to define things like this with better detail and more 
interoperability for SVG 2.0.

To some extent, making SVG 1.1 more precise risks making existing UAs 
unconforming, which is less of a concern for SVG 2.0.

As far as adding the link you suggest, I don't see any harm in that.
