Why the aggregated feature is "OGC Simple Compliant"?
First CREATOR generates a box POLYGON(0 0 10 0 10 10 8 10 0 10 0 0) and the second one a triangle (POLYGON(0 10 5 13 8 10 0 10)).I think I missunderstood the meaning of "OGC Simple".(the opposite of a complex feature?).It seems that "simple" doesn´t imply "valid".

Thanks in advance.
we could definitely add some clarity to the FME user documentation on the GeometryValidator - which simply refers to the OGC simple feature specification:http://www.opengeospatial.org/standards/sfa
_____________________________________________________________
isSimple Checks for OGC simple (taken from geosdll_api_geom.h::isSimpleWithInfo):
if multipoint,check for repeated points
if anything else,check for self-intersection
_____________________________________________________________
isValid Checks for OGC valid (taken from isValidOp.cpp::checkValid):
if point,check for Invalid Coords
if lineString,check for Invalid Coords,too-few-points,
if linearRing,check for Invalid Coords,closed rings,too-few-points,self-intersecting rings
if polygon,check for Invalid Coords,closed rings,too-few-points,consistent areas (intersecting or duplicate rings),self-intersecting rings,holes in shell,nested holes,connected interior
if multiPolygon,similar to polygons,but also checks if polygons intersect each other
if GeometryCollection,break apart,the check based on geometry type
