    v3 v4  
    1919 * '''More Validation Feedback'''
    2020  * The isValid() function can tell me if a geometry is not valid, but it cannot tell me '''why'''.
    21   * Perhaps an isValidLocation() or isValidReason() to show where and why the geometry is not correct.  The JTS workbench has some of this functionality, so hopefully it is hiding in GEOS somewhere.
     21  * Perhaps an isValidLocation() or ~~isValidReason()~~ ('''DONE in PostGIS 1.4, GEOS 3.1.0 -- but would be nice if gave all invalid locations -- just gives first ''') to show where and why the geometry is not correct.  The JTS workbench has some of this functionality, so hopefully it is hiding in GEOS somewhere.
    2222  * Also, by combining snapToGrid, buffer(0.0) and some other evil stuff, it should be possible to write a cleanGeometry() function that "mostly" works, and "mostly" is better than nothing at all.
