Maybe the left parenthesis is the error. Then you would read :
((0 0, 1 1, 1 0), 1 0, 0 1)
Then three points between parentheses make a curve, and points 
outside are segments vertices ?
Just a guess.

I found this : http://www.wiscorp.com/2CD1R1-03-spatial-2001-12.pdf
but I was too lazy to read it ! ;)
