Hi list and Chris, this is what i was asking :D
i was thinking that boundary is part of the geometry, so if there is some geometry on the boundary (in this case, a point on the polygon boundary) then the point is within the polygon. But after your message i read the specs (http://portal.opengeospatial.org/files/?artifact_id=18241) about within, i see the relate and now i understand. Thanks for the hint Chris.
