Comment (by darkblueb):

 Testing dataset **Valids-Delft** for valid-invalid policy evaluation,
 under construction [https://trac.osgeo.org/geos/wiki/Valids-Delft here]

 Currently all Valids-Delft tests use counter-clockwise winding for outer-
 shell, and clockwise winding for inner-shell(s). Permutations of winding
 are planned.

 **DrJTS** says:  JTS will continue to be insensitive to windings at this
 time  (sep19).
