When I did some testing of SVG a few months ago (in preparation for 
Opera's SVG release, and in relation to Mozilla's SVG work as well), I 
found many tests where I couldn't find a single correct implementation. 
When speaking to implementors about this, they all "explained" what the 
SVG spec meant in contradictory ways. (I stopped trying to make tests when 
I found that the spec itself was so vague that making tests was nigh on 
impossible, and instead started sending last call comments to get these 
issues resolved. These are now being rejected. Go figure.)
