I don't think that the "touching inner ring" issue was ever limited to 
"two or more consecutive points". Your page is the first time I read this.

Personally I don't consider the "8" shapes valid - and I don't think 
there's a difference between the one with a node in the middle and the 
one without. I don't consider the "inner ring touching outer ring in 
single point" case to be valid either.

Bye
Frederik
